I think that the visual are great, although I also do understand the criticism of some comments that some sprites are stylistically not matching, but this is a jam game after all. As of now I dont see any reason why crouching is in the game, since the player sprite does not really change in terms of size, although as a player I am not able to see the corresponding colliders. The overall take on the topic is extremely cool, but the knockback of some enemies really was immersion-breaking for me.
Nonetheless: great Game!
