Had a lot of fun with this one on my stream. I really like the main character art and the enemy art. I also think the platforming feels pretty good. Shooting the laser attack also worked well. I also like how big you were able to make the levels!
For feedback, I have a few things. The melee attack feels weird to me. Since there is no animation for it, I have a hard time seeing what/how far I am actually attacking. The character controller is a little floaty. I saw in a video about making good platformer controllers that to fix this feeling a character should experience gravity at an increased factor, but only when falling. So once they jump reach the peak, then switch the gravity to the heavier fall gravity. It allows your jumps to feel jump but your player to feel like they are under control.
Fun submission, good job!
