I really enjoyed the atmosphere! The music is good, and the graphics supplement it nicely, I just wish there was some animations (you can do nice things with just some squash and stretch). The gameplay is classic but well executed. I just wish the cooldown on the primary skill was much much shorter, it doesn't feel good to just run around and do nothing. You would have to balance around that to make it not overpowered, but the fact that you need to get close while every enemy can shoot you is already a good limitation. I really enjoy the skill that let you explode controlled enemies, it's the little thing that makes it stand out!
Really good entry, well done!
