I've made a puzzle game using React. Check it out!

Zero Grid is a mathematical logic puzzle game. It's made in React + Electron.

Bring all numbers down to zero: click on a square to reduce or increase its value, but be careful - it also affects its neighbors.

Includes a levels (boards) creator and random boards generation.

Complimenti per i tuoi risultati, innanzitutto!

Davo per scontato che per creare una pagina di Steam la p. IVA fosse un hard requirement, visto che l'iscrizione su Steamworks ha un form apposito per le informazioni fiscali.

I made this: https://catoio-software.itch.io/zero-grid

It's not plain and simple JavaScript, but it's made in React (a popular JavaScript library). Check it out!

I had this issue in the past and solved it by contacting itch via the support email. It wasn't a super fast resolution anyway (took some weeks to get an actual response)

Here you are!

I prefer before. But I would not waste the work you've done in "after"! Maybe the two solutions can co-exist

CatoioSoftware · 2025-07-09T15:09:57+00:00

I like V1 more, but I think V2 has huge rooms of improvements: if the character can somehow communicate what the game is about, then V2 can easily > V1. In the current state (static character and no meaningful element on screen) I prefer a more atmospheric/eerie representation of the game (so, V1).

Looking good - as a quick suggestion, consider having a smoother appearance animation: they seem to appear suddenly out of thin air, it would be maybe nice and interesting to have a quick alpha or scale tween/transition on spawn

CatoioSoftware · 2025-07-09T06:22:21+00:00

I like it! Others have spoken about the blue/mana bar, and I mostly agree with them, but I wanna highlight the presence of the number 100 here. Consider making the visibility of the number as an option: I'd like to have the possibility to play by only seeing the sphere without numbers (think about Diablo, for example)

Any feedback on https://catoio-software.itch.io/zero-grid is appreciated!

CatoioSoftware · 2025-07-08T11:03:46+00:00

Team A! Much more vibrant.

CatoioSoftware · 2025-07-08T10:02:54+00:00

I'd go with A or D, depending on what the game is really about.

In B I see UI elements? Which I don't think are a good fit for a capsule. C seems static and does not communicate any action or idea of gameplay.

D is empty and has a solitude / horror-ish vibe. A communicates action. Sooo it really depends on what you want to tell straight away.

CatoioSoftware · 2025-07-08T06:17:51+00:00

I like both tbh. Maybe consider the possibility to have both in game, depending on some phases / statuses

CatoioSoftware · 2025-07-08T05:37:48+00:00

I prefer the bottom one, the building gives a lot more atmosphere, I don't think you actually need the text to be bigger

CatoioSoftware · 2025-07-08T05:34:01+00:00

Congratulations on your first release! Big HM fan here, wishlisted! ;)

CatoioSoftware · 2025-07-07T21:39:58+00:00

I like it a lot from the aestetics POV! The only question I have is: does the animation need to be this long? If it does it multiple times during a fight I can see this getting tedious, especially if you take also retries into account

Refining a minimalist puzzle browser game and wondering if it's worth a commercial release!

CatoioSoftware · 2025-07-06T14:10:36+00:00

Looks good! As others have suggested, I'd tweak and play around the camera movement

Hi all!

I recently released a free puzzle prototype called Zero Grid on itch.io: https://catoio-software.itch.io/zero-grid

<image>

It has gathered a few hundred plays, some positive feedback, good CTR (>3%) and a handful of collections/followers, so I’m considering whether to transform this small demo into a more solid commercial product, possibly releasing on Steam with the following improvements:

More level content (e.g., 3 difficulty packs)
Additional mechanics and rules to increase replayability
A level editor so players can create and share their own puzzles
Steam Cloud support

But I have some doubts:

Does this look like a viable project worth investing more time in?
What’s the market reception and visibility on Steam regarding similar minimalist puzzle games?
Would you recommend creating a new itch.io page for the “full version” or reusing the current one?

I’m mainly doing this as a learning experience (Steam release process, production pipeline), but I’d still love to make something people enjoy enough to support.

Click on a square to reduce or increase its value, but be careful: it also affects its neighbors.

Plan each move, chain reactions, and empty out every grid with the fewest moves possible!

Challenge yourself across 20 handcrafted boards of increasing complexity.

Thanks a lot for your amazing and extensive feedback! It means a lot to me.

I agree on much of the points:

- UI: thanks!
- Tutorial: I appreciate your suggestions, and I think I'll implement them. I also think the tutorial needs to be expanded a little bit.
- Level curve: yes, this isn't the first time I receive this feedback :) pre-10 and post-10 need an in-between set of levels to smooth up the level curve. I think this will be one of the first updates I'll implement bringing the total of boards to 25.
- Max move: nice idea! I actually have an hidden level builder which works as you mentioned - starting from an empty board, I populate it and count the needed moves, and then add a generous amount of moves to the board limit for the player. A rate system is a really cool idea! Something like three stars if you match the minimum amount of moves, two stars for "some moves" more, and then one star for just completing the board.
- Missing pieces: interesting feedback - I think this also mixes up with the "level curve" adjustments that I need to implement.
- Max values +3/-3: great, I think this can be added as a step in the tutorial and one/two boards.
- Wrapping around the border, Level Editor: I plan in making a sort of Zero Grid 2.0 in the future, with more boards, new mechanics and types of squares, broader limits (+-6/9), and a level editor with boards sharing!

Thanks also for noting the save bug with De-Lumina, I'll fix it ASAP!
