I agree with @IvanM71. The bindings are kind of hard and that makes your game kinda unplayable and unfun to play. One solution would be to just use the right mouse button to switch around the abilities. Since you don't have a lot of them, I think that wouldn't be such a bad alternative to what you currently have. I bet that would make the game more playable. You can probably still update it even though the jam is over with. I do love the music and sound effects you put into it though.
