Graphics look nice and you can tell everything apart. You should offer a way to remap the controls. I found this game to be very easy. You should offer several difficulty levels from Easy to Very hard.

Recoil is so annoying
Ctrl to punch? What's next? Alt + 4F to walk?
good game
I am going to be harsh on this, This game is WAY TOO EASY, as long as you keep jumping and walking the enemies will never hit you, giving enemies some firearms would solve this problem, but even if you manage to get hit, (which is once in a blue fucking moon) you just wait a second and your health will recover.
The only times I managed to die was when I missed a jump and once against the boss because his shotgun blasts do a shit ton of damage.
Hopefully this is improved on in future games.
