I played for about 15 minutes, and first of all, I love the vibe. The UI and overall visual style are really good.
Player onboarding or a short tutorial would help. When I reached the initial character selection screen, it was not immediately clear what everything meant. Given the game’s arcade-like feel, leaving some mechanics open to discovery could work, but I would still provide players with a little more guidance upfront.
The procedurally generated shapes and their spacing could use some refinement. Since many obstacles include openings or paths through them, navigating those paths should feel like a risky but viable option, not something players should always avoid. Ideally, a skilled player can navigate them consistently, while a desperate player still has a small chance of barely scraping through and escaping. Those close-call moments would feel great.
For example, shapes like this should provide a slightly more forgiving escape route:
Regarding AI-assisted development, not sure where to start. I am a developer in my day job, so I already know what to look for and how to communicate with AI. My general advice would be to spend the time saved on coding grunt work to instead work on building game design doc. Ideally, you should be able to design most of the game on paper, or at least describe it clearly, before handing implementation work to AI. AI can also help refine the math and other design details.
Overall, this feels like a fun take on Snake.io. I could see a casual or most gamer-type people picking it up for quick sessions. I would also love to see a massive, possibly procedurally generated map that expands as more players join.
Very cool idea overall. I could offer more specific feedback depending on the direction you want to take it.
