Awesome game! The controls feel great and the graphics are decent (even if the enemies look like they're constantly asserting dominance...)
When you finish a stage, it's a bit awkward since you instantly get teleported to the next level. Maybe you could've made it like the Game Over scene where if you finish a level you have to press a button to proceed?
The music was a bit repetitive but I really liked the last level, it was a nice change of pace! The credits were funny too.
Good job on this one! :3
