This game has a lot of potential to be something really cool, the art is awesome and theres a lot of soul here
that being said, it has some problems
As it stands now, the pacing is poor; its almost impossible as a new player to tell whats going on before you get instagibbed by something. Having the player start out on a lower stakes floor would help a lot
There are perks you can collect, but because of how hectic the gameplay is, you have no time to read or think about what youre collecting. What if you slowed the game's timescale down when reading item descriptions for perks? This way you still have to be careful, but you have a little more reasonable amount of time to think about the item
The movement/physics feel at odds with the nature of the game. A game like this could really benefit from some more smooth fast paced movement IMO
