Hi there. Just played your game, I really like the art style.
First thing, I think if the enemies were in a slightly different shade, it would really help in terms of identifying the player and enemies on screen.
Also sometimes the hits don't seem to connect most of the time. Regarding the hit sound effect, I feel like it plays a bit too early and should be changed to start as soon as the Attack has been hit...
There some minor issues like animations not working, but I can't really complain because it was a 48 Jam. If you do consider coming back to update it, I suggest that and maybe a small Game Over screen.
Also I think there was a wall in the top right side of the map missing and I was able to leave and explore the outside... I'm guessing one of the level editors got tired and forgot a wall XD
Overall, good job and I look forward to seeing your future titles.
