A slow day at the office

Nicely done, I really like the art. It feels a bit hit or miss like I'm just getting lucky when I complete the levels.

I cannot walk, player not react on WASD or other keys. It's a bug, or what i fix that?

Sometimes the player moves by himself even if I pressed another movement key it won't change its course.
Overall nice game but I think its too basic, maybe you should implement some other enemies or weapons.
