Hi everyone, I built FuseCells, a minimalistic logic puzzle game where every level is handcrafted (no procedural generation). It started as a personal challenge to design a clean rule-set and scale it to thousands of puzzles without losing difficulty balance.

What’s unique: • 2,500 handcrafted levels across multiple grid sizes • Deterministic logic — no guessing required • A rule system inspired by constraint-solving and path-finding concepts • Daily challenges and global progress tracking • Fully built as a solo dev project

Technical notes for those curious: • Level generation tools I wrote validate solvability using a custom constraint solver • Difficulty is estimated via step-count of the solver • The game is optimized to run smoothly on low-end devices • Designed first for iOS, now fully adapted for iPad as well

I’d love feedback from puzzle lovers, game designers, and anyone interested in handcrafted logic design. Here’s the App Store link: [inserați linkul]

Thanks for reading — happy to answer any technical questions!

I’ve enjoyed the game so far, one minor thing: there seems to be multiple puzzles back-to-back that are essentially just the same pattern as a previous puzzle rotated.

I’m not saying you can’t/shouldn’t do this but they should be spaced out more. It not fun to finish one puzzle then realize for the next one: “oh, it’s the same puzzle rotated 90/180 degrees”.

Additionally, I understand the 4 vs 8 surrounding block distinction but I wonder if it makes sense to do both. I found it a little annoying to have the rules change like that just as I was getting the hang of it. I could be wrong here and maybe you still want the ramp-up in difficulty but I’d almost prefer moving from 4->8 during the tutorial and never going back. But that might just be me.

Lastly, I agree with another comment here, make the initial few game count closer to 10 before the CTA. I wasn’t ready to make a decision after just a few games. Maybe even wait till the user finishes the first set of levels? Obviously they can choose to upgrade at any time but the CTA seemed too early.

Hello! Thank you for your nice feedback! It's first version of the app, so I will try to make much possible like you say, very good point!
