I really like this game, but I feel like it could be much better. The controls feel kind of clunky at first, as you gain speed very fast while in the air and feel really sluggish on the ground, and I couldn't figure out how to shoot on the keyboard, so I had to play it with a controller. It would help if you had a controls editor for the keyboard, or...
Congratulations, the game is very well done!
short fun game did 20 lvls in 2 hours, got all achievements, controller is a bit off but works.
