Nice work. The game was quite difficult so I didn't get very far.
Your game has a nice look and music was good too. Overall good job with the atmosphere.
I think think the controls could be a little tighter and I think you might be better off focusing on the shooting as it is quite interesting and pretty well implemented. I think you might be able to come up with even more interesting uses that way. I don't think you need to focus as much on precision platforming or melee attacks. Focus on what's unique.
Well done.
