Vibe Building a 2D game with AI

I’m building a game called Infinity Grid, and I’m doing it with AI at my side. Instead of sitting down with a single engine or toolset, I’m documenting the process of experimenting across different “vibe coding” platforms—those strange, half-magical spaces where you describe what you want, and code, art, or mechanics take shape.

The idea is simple on the surface: a 2D endless platformer full of geometric walls, shifting illusions, and coins to collect. But the real story is what happens behind the curtain—me testing how far AI can stretch in game creation, where it shines, and where it falls apart. Infinity Grid isn’t just a game; it’s an experiment in building with machines, documenting both the breakthroughs and the brick walls.

About

Introducing Infinity Grid: The Endless 2D Illusion Platformer

A new 2D platformer is here to melt minds and test reflexes. Infinity Grid drops players into an infinite world of geometric walls, shifting illusions, and deceptive paths. Every level is procedurally generated, meaning no two runs are the same.

Players choose their character, leap through traps, and collect coins scattered across maps that bend the rules of reality. Invisible walls, collapsing floors, and portals keep each moment unpredictable, while minimalist art and smooth mechanics make the challenge feel sharp and addictive.

With unlimited levels, scaling difficulty, and illusion-driven surprises, Infinity Grid isn’t just another coin-grab—it’s a psychological gauntlet disguised as a simple game.
