Insane level of polish for a jam game, art style is very cohesive and cool, I could easily see myself buying a commercial game that looks like that. I especially like how you made arms, the only thing that looks like it has depth in the entire game, but still works very well with the rest of the art. The only thing I could ask for is for you to go a bit crazier and more actiony/violent and snappy with the audio, both the music and sounds feel a bit tame in contrast to your energetic movement options and constant running and gunning. Also (and this is totally a personal preference) I would remove the use button entirely, opting instead for shooting/dashing through doors and exiting the level upon contact. I feel like getting close to doors and pressing a button and then waiting for it to open slows the pacing a bit. Anyway, amazing entry!
