If there was an UI category you'd definitely win. The game it self is also pretty enjoyable (I loved it), nice gameplay, however, there are some bugs (The health going over a 100% , a zone on the bottom of the arena that is blocked by the UI and if you kill someone there you cant loot him and the fact that the endless mode, well, ends). Besides fixing this bugs the only thing I'd change would be how long it takes to level up the weapon and spawn the first flamethrower, i think it takes way to long.
EDIT: My bad, I had the old version, the bugs I pointed were indeed fixed, and the game is awesome!
