This game is pretty cool. I really love the animations for the melee combat. Not only do you have the single punch, but you implemented the full combo if the button was pressed quickly enough. I liked the binary lock doors. Also, if you jump left and right repeatedly, it looks like the Six Flags Guy dancing, which made me laugh.
Like Dysfunc, i got a few null reference errors in the console. It happened to me whenever I died near a locked door. The Lock UI would stay with my character on revive and when i would complete the lock, then the null references would happen.
Overall, I liked this game!
