Nice game man. Congratz :)
I would improve only one thing that in my opinion would make it a little more fun.
- The ability to shot the gun with Space bar or Right Ctrl)... This way you can play with only one hand (WASD+Space bar) (Arow Keys+Right Ctrl)
And Ive noticed that there is a bug that you cant jump while toutching boxes.. Maybe its the pivot from the player that is geting inside the boxes? Ive noticed that when you turn left>right or right>left your character moves a little, its probably a pivot problem.
Please play my game and give your honest feedback :)
