I keep a few simple rules up my sleeve. First, every sprite or tile is stored as an immutable file in a versioned repo, so I can roll back if something goes wrong. I also lock the asset folders with read‑only permissions for anyone who isn’t part of the core art team. To catch any sneaky changes, I run a hash check on the archive before each build, and if the checksum doesn’t match, I’m alerted immediately. Finally, I build my worlds in modular layers—background, midground, foreground—so if a glitch pops up in one layer, I can patch it without scrambling the whole scene. It keeps the colors crisp and the story intact.
