What changed between the demo and the full release
If the demo put you off, the useful question is narrow: was your problem fixed. The developer answered that a piece at a time, scattered across 38 Steam threads and their Discord. Every answer they gave is below, in their words, with the thread attached.
20 stated differences, by how firm the claim is
- 6 stated fixed
- 9 deliberately changed
- 4 promised, not dated
- 1 claimed fixed, disputed
Nothing here has been verified in the release build, because nobody outside the studio has played it yet. Stated fixed means the developer said so. Disputed means players reported the same failure afterwards.
Last checked against the Steam threads and the official Discord on
The single most useful thing the developer has said about the demo is that they deliberately stopped working on it:
“we know, nearly every bug is already fixed, but we focus on delivering bug-less full release in stead of fixing demo”
Official Discord, #general, 24 August 2026 — no public link, server members only
The boat itself
“We figured out what made this issue occur --FIXED--”
claimed fixed, disputedIn the demo
Boats detonating or being flung into the air, most often after items were left loose on the deck.
In the release, per the developer
The developer worked through this one in public: first asking whether it was the harpoon, items or movement, then reporting a collision and physics pass, then marking it fixed.
What happened next
Players posted the same failure after Hotfix #5 was announced as the fix — “The moment you place something on the boat (Dropped) The boat explodes after a short time.” On 25 August the developer went further than any earlier reply, naming the cause and calling it completely fixed: “items + boat physics + replication was a complete nightmare (for instance 1 kg item was able to throw 4 000 kg boat like it’s a feather etc.), but we fixed them completly and added a lot of storage for convinience”. That is still a claim about a build nobody outside the studio has run.
“Yup, we noticed that, this is already fixed.”
stated fixedIn the demo
After one update the harpoon turret read “Use Harpoon Turret (Occupied)” and could not be used by anyone, in solo play as well as co-op.
In the release, per the developer
Acknowledged and stated fixed.
“we'll give them 2 modes: standard and aggresive one + you are able to mount more harpoons … on slots on the boat”
deliberately changedIn the demo
A single harpoon behaviour, and one mounting point.
In the release, per the developer
Two pulling modes, and more harpoons mountable on the boat's slots. The modes shipped as Rapid Mode and Slow Mode in Hotfix #6; the developer's own wording while building them was “standard and aggresive”.
“It already got fixed in today's update”
stated fixedIn the demo
Slapping a player standing on the boat could drop them through the deck, fling them into the sky, or destroy the boat.
In the release, per the developer
Fixed in an update during the demo period.
Playing together
“Yup, its fixed in full game but not in demo yet”
stated fixedIn the demo
A patched hole stayed visibly open for the other player, and vice versa — each crewmate saw a different boat.
In the release, per the developer
Stated fixed in the full version.
“4”
deliberately changedIn the demo
No crew size stated anywhere. The store page lists Online Co-op and stops there, and it was the single most asked question about the game.
In the release, per the developer
Asked “How many players max?” in the official Discord, a developer answered with one character: 4.
Official Discord, #general, 25 August 2026 — developer NieBieSkyy (no public link — server members only)“Networking had been significantly improved.”
deliberately changedIn the demo
Rubber-banding and desync bad enough that players recommended against co-op.
In the release, per the developer
Replication reworked, then reported as significantly improved.
Performance
“we know, nearly every bug is already fixed, but we focus on delivering bug-less full release in stead of fixing demo”
deliberately changedIn the demo
Players kept asking for the demo to be patched.
In the release, per the developer
The developer said outright that they stopped fixing the demo in order to ship a clean 1.0. That reframes every remaining demo bug: most are not unsolved, they are unshipped.
Official Discord, #general, 24 August 2026 (no public link — server members only)“Demo version is severly unoptimized in comparison to full release”
deliberately changedIn the demo
GPUs pinned near 100% with the game open. Separately, and in a different thread, players reported 20–50 fps on hardware well above the minimum spec — see /performance, where both threads are cited individually.
In the release, per the developer
The developer describes the demo build as far less optimised than the release, and separately said CPU was the bottleneck they were working on.
“just lacks signature of a company”
promised, not datedIn the demo
Error 0x11c7 on launch, which the developer had previously put down to Smart App Control, antivirus or corrupted files.
In the release, per the developer
A sharper explanation, given on 25 August: the executable lacks a company signature and Windows 11 Smart App Control blocks it over a new Microsoft certificate. The developer said they would take care of it rather than leaving it to the player, and put the scale at two reports against more than 100,000 demo players.

Carrying and items
“In full release we've added plenty of space in the boat + now you can instantly pick up scrap to the boat.”
deliberately changedIn the demo
One item in your hands at a time, and nowhere to put anything down. The most-upvoted request on the whole Discord is an inventory.
In the release, per the developer
More storage space on the boat, and scrap can be picked straight up into the boat rather than carried.
“In a nearest update (today) we will change fishing rods and flocks. We also enhanced items' collisions.”
promised, not datedIn the demo
Loose objects, fishing rods worst of all, rolling around the deck and clipping into the hull.
In the release, per the developer
Fishing rods and flocks to be changed, and item collisions improved. The wording is future tense — this was announced as an upcoming update during the demo period, not reported back as done.
“That will be fixed in next update”
promised, not datedIn the demo
Putting a stacked item — a wallet, bait — into an empty slot on the table set its value to −1.
In the release, per the developer
Stated fixed in the next update.
Controls
“In demo - no, but there will be in full release.”
deliberately changedIn the demo
No controller support at all.
In the release, per the developer
Full controller support, and the store page additionally lists DualShock and DualSense.
Fishing
“🤣 we fixed that in full version!”
stated fixedIn the demo
Dropping the fishing pole could leave you unable to pick it back up.
In the release, per the developer
Stated fixed in the full version.
“it's been fixed in full version”
stated fixedIn the demo
A state where fishing simply would not start.
In the release, per the developer
Stated fixed in the full version.
What is out there
“we'll add more repair materials on map and more checkpoints to make the game less frustrating”
promised, not datedIn the demo
Players ran out of repair materials at the minefield with no way to restock and no checkpoint to fall back to.
In the release, per the developer
More repair materials placed on the map, and more checkpoints.
“it's pretty bugged in demo, in full release it looks completly different”
deliberately changedIn the demo
The jump after the minefield: players repeatedly hit the wall no matter how early they turned.
In the release, per the developer
Described as rebuilt rather than patched.
Official Discord, #general, 24 August 2026 (no public link — server members only)“and most importantly - your own crew”
deliberately changedIn the demo
A player looking at the store page said they could see no dangers or challenges at all.
In the release, per the developer
The developer answered with a list: jellyfish, sea mines, enemy fish, thunder, lava, the boat and you catching fire, boat jumps, caves full of falling rocks, and Laba the frog — plus, in their words, your own crew.
“you have to turn on lights after turning on the engine”
stated fixedIn the demo
Objects glowing in the dark, and a night so black players could not play through it.
In the release, per the developer
Glowing objects fixed. On darkness itself the developer judged it bright enough after seeing screenshots, and pointed out that the interior lights only work once the engine is running.
How to read a claim like “fixed in full version”
It is not evasive — the studio has been unusually direct — but it is a statement about a build nobody outside the studio has run. One item above was announced as fixed and then reported again by players, which is the normal shape of a physics bug rather than evidence of anyone lying.
The one to watch is the boat destroying itself. It has the longest thread, the most reports, and the most confident fix announcements. If it survives into 1.0 it will be the first thing anyone writes about. There is a full breakdown of the triggers if you want to know what to avoid in the meantime.
What is still unanswered
Some questions have no right-hand column because nothing was ever said in reply. Clearing algae off the hull was asked in the “boat won’t move?” thread; how the rudder and propellers are maintained, and switching the microphone device, were both raised inside longer threads that moved on without addressing them. They are not in the list above because there is nothing to put opposite them.
Demo and release, in short
+Is the Water You Doing? demo the same as the full game?
No. The developer stated in the official Discord that they stopped patching the demo in order to ship a clean 1.0, so demo bugs are mostly fixed-but-unshipped rather than unsolved. They also describe the demo build as far less optimised than the release.
+Was the boat explosion bug fixed for the full release?
The developer marked it fixed twice, first with Hotfix #5 and later with a note saying they had found the cause, and on 25 August named the cause outright: item physics against boat physics, where a 1 kg object could throw a 4,000 kg boat. Players did post the same failure after the Hotfix #5 announcement. Until someone plays 1.0, treat all of it as claimed fixed rather than verified.
+Does the full release have controller support?
The demo has none. For the release, the developer said it will and the store listing carries Full controller support along with DualShock and DualSense — that is the listing’s claim, not a tested result, because nobody outside the studio has played 1.0.
+Did they fix the one-item carrying limit?
They changed it rather than removed it. The developer says the release build adds much more storage space on the boat and lets you pick scrap straight up into it instead of carrying it by hand.
