I really liked what you were going for, but without the enemies moving towards me I didn't really feel any sense of challenge. I liked the overall look of the game, but would love to see more. Adding a hot key to reload would help with the pace as well. 

Tried it, the enemy ai seems to have bugged out on me though, since they never moved from their spawn points, so I was free to shoot and wait for the timer to tick down

The staticness of it is awesome. Changes everything in a way and makes you think a bit different. I like it. Good fun :)

Now that was just good fun. Be great on mobile :)

I love the idea on this one and the fact that I don't control the movements are really interesting. I think this could be a really fun game once some of the bugs are fixed up.
