Really cool entry!
I especially liked the level design which allowed some cool stuff to happen. Especially at level 2, were you could speedrun the beginning (by crouch + jumping), then using the slowmo to shoot at the barrel during the jump... felt great! =p
Also it gave me nostalgia of some flash games I used to play with stickmen like this haha!
Difficulty ramps up really fast though :)
Well done, nice game!
