This is not as much a game as it is a proof of concept/tech demo, although playable and possible to finish.
There's one functioning enemy and a boss that doesn't take that much effort to beat, functional moving platforms and sliding doors. That's about it. Had no time to implement even the simplest SFX or background music, nor replace any of the placeholder graphics.
Technically there's controller support too but uh, it's hard coded for gamepad slot 4 (DInput), and it's super awkward. The game plays better on keyboard and mouse.
