The process, the bugs, and the mistakes I made so you don't have to.
I rebuilt my save system three times — the third one stuck
JSON, then binary, then a versioned custom format. Why a corrupted save is the bug that hurts players the most.
6 min read →How I draw 400 tiles without losing my mind
Locked palette, strict grid, and a script that generates variations automatically. Free template at the end of the post.
4 min read →Coyote time, jump buffering, and why your jump feels wrong
Three lines of code separate a stiff platformer from one that feels great. Copy-paste ready code included.

8 years making games.
8 years making games.
Open sourcing them since day one.
I started alone — no course, no money, and nobody to ask. Every asset I need, I make. And every asset I make, I give away — because the version of me from 8 years ago would have quit if other people hadn't done the same.
Today I split my time between shipping my own games and maintaining an open library of sprites, sounds, shaders and templates that has already helped thousands of devs get their first project off the ground.
