I really like the music, it changes key in a nice way!
Also super cute graphics, love the fist fighting animation and facial expression.
I do not love the deceleration when letting go of left/right.
Nice with some education in binary numbers when unlocking doors :D
Eh, I triggered a bug and got a lot of NullReferenceExceptions when I hit a door after unlocking it I think... I'll try again...
I got the high jump, but bugged out again. The crouch, awesome really! I noticed that when opening a door, people on the other side start shooting me from another room :S
The presentation is super strong, sadly it loses some on being buggy.
