I played for a bit now and, first of all, I like that the character in the lobby is called Ubuntu :D
The game feels so fricking goooood!!! Buuuut, e.g., the lobby couuuld maybe look a bit friendlier and nicer, also differenciating to the rest of the rooms!
Your HP is a bit "hidden" in my opinion, so a bit difficult to see in the bottom right... Maybe put it in the top left or top-middle!
Slashing through the enemies already feels VERY cool BUT maybe reward the player when they killed an enemy?
oh and also the sfx could use some rework?
Overall an extremely juicy feeling, cool game!
