Neat sidescroller.
The visuals look good and the music was a nice choice. The sound is decent also the slashing gets a bit repetitive.
I feel the attack should have been a bit quicker. Also, I understand not moving while attacking on the ground, but it felt weird to be stopped from strafing forward in mid-air because I attacked.
Variably timed jumping would have been nice too; that is it would have been nice to be able to stop jumping up early, feels "tighter" that way imo.
The slimes were cute. Two characters to choose from was cool, don't see that a lot in game jams. It's nice of you to have a controls tutorial in the actual game.
Cool submission.
