Above saltiness aside, are you worried Microsoft will see this?
The hard parts for me were describing bugs that weren't visual and the more subjective stuff, e.g. where memories should go, pacing, what felt confusing, whether something was actually fun, etc. I couldn't have built this without AI.
Regarding Microsoft: a little. It's noncommercial, and I have a credits/disclaimer screen that makes it clear it's an unofficial fan project and that the Halo assets belong to their respective owners. But obviously that doesn't mean I own or have a license to the Guardian assets. If Microsoft/Halo Studios asked me to take it down or change something, I would.
