Ok so the game is great, but here is some things you could add to the game that would be cool:
Limit the number of double jumps you have on each surface you touch, beacause right now you can just climb walls spamming the space bar
Add some flying or rocket shooting enemy, so when you stop time you could shoot the rocket and make it explode
Make the bomb enemy explode when shot, so you could lure him into a group of enemies and shoot him, adding a bit of strategy to the game
