Nice! I had a big problem though where my mouse wasn't locked to the screen so I kept accidentally clicking outside the game

This was fun - an ammo counter would have been great though, and the slow time ability appears to slow the player down too - negating any benefit. Just like King said, reminds me of doom too. Good music, fun gameplay, i got up to about 350 before my kiting strategy buckled. Nice work.

I didn't really use the time slow ability. Maybe make more of an incentive to use it. Also some more enemy variety would be nice. Over all, great game! Reminds me of doom.
