Yea, it definitely needs sounds and I will add those in a post-jam version.
You can actually shoot the parachute guys with the top gun (shift) cause that doesn't just do damage when it hits the floor.
And I might have to experiment with making what ability you lose random, that sounds like it could help. For the post jam version I was kind-of thinking about giving the player the option to rearrange their abilities or swap them out for different ones in between games.
