Water TD Patch Notes: 1.0.1 Changes and What They Mean
Everything in Water TD patch 1.0.1: Reverse whirlpool fix, Napalm spread, 60-turret display, Undertow nerf, Black Hole buff and the balance behind them.
Water TD launched on 13 November 2026 and received its first patch the next day. For a two-day-old game that is a good sign, and the contents of 1.0.1 are a useful map of what was broken and what the developer considers balanced.
The bug fixes
Reverse whirlpools pushed off the map. If a Reverse whirlpool left the playable area, the level could not finish, because the game waited for a wave that would never arrive. On 1.0.1 this is fixed. On the launch build, avoid stacking push effects on a whirlpool near a map edge.
Napalm fire landing in a line. With many turrets firing at once, fire patches landed in a single line instead of spreading across the impact area. Fixed.
No damage or kill numbers above 60 turrets. Dense late-game layouts stopped showing damage and kill readouts. Fixed, which confirms that sixty-plus turrets is a supported scale rather than an edge case.
START immediately after restart. Pressing START right after restarting a level began the wave before the turrets were back. Fixed.
Every one of the four is a scale or state bug, not a content bug. That tells you the flood simulation and the turret count are the parts of the game under the most load.
The balance changes
| Change | Direction | What it means |
|---|---|---|
| Undertow takes 1/4 of the water's current HP, not max HP | Nerf | Undertow no longer scales with a full-health wave; it is weaker against damaged water and weaker overall |
| Auto Damage III and IV | Buff | The default turret's top damage ranks hit harder |
| Black Hole damage per tick | Buff | The hole kills faster |
| Black Hole pull strength | Buff | It captures more of a wide front |
| Black Hole close placement | Restored | Stacking holes is viable again |
| Hole Range cost | Nerf to the upgrade | Range is now a trade, not an automatic buy |
| Fork fire rate | Buff | The Fork node fires faster |
The Black Hole cluster is the most consequential. Buffing damage, pull and stacking while raising the range cost is a deliberate redesign: the ability should be a close-range volume tool, not a long-range safety net. The Black Hole guide→ covers the new placement logic.
The Undertow change is the opposite kind of statement. Taking a quarter of current HP instead of a quarter of maximum HP means the ability's value falls as the water is damaged, which makes it a finisher rather than an opener.
The launch-day numbers
The developer's second news post reports over 5,000 users on day one. For a solo-developed tower defense game with no marketing budget, that is enough to justify continued patching, and the post lists balance work, bug fixes and a level editor as the roadmap.
The same post is the only public statement of intent so far. There is no announced content expansion, so treat the campaign as the content and the editor as the long tail.
What is not in the patch
- No new maps or turrets.
- No erosion toggle, despite a community request thread.
- No control changes, despite a request for right-click and WASD panning.
- No Mac or Linux build.
- No stated Steam Deck rating.
The developer asks players to report bugs by pressing F8 in game or posting in the official Discord: discord.gg/7pKcGrhXJ5 ↗. That is the fastest route to a fix given the patch cadence.
Should you update?
Yes, and not only for the fixes. The Black Hole buffs and Auto damage ranks change which builds are efficient, so a guide written on launch day is describing a different game. If you are following any Water TD advice, check its date against 14 November 2026.
The black hole guide→ explains the buffed ability, reverse→ covers the whirlpool fix, and turrets→ lists the affected weapons.
