ya' know what, you should make .. a final level to complete the game ! an epic end, or whatever.. the big showdown with lots of guns and shadows and lights and sh*t like that !
I first played it and the attackers were easy; second time i played it (new game) , the attackers were heavy on the third time already.. wtf man ? there was a man with a chaingun on the forth attack, I mean the first time there wasn't one even in the 8th attack ... how ? why ?
what if, when you get far enough a new square comes along ; this way, as you get further, you can get more points, but there's a bigger chance of getting hit :D , huh? .. But.. that would take away the 'relaxing' part of it.. how 'bout a sequel ?
this is in need of a restart button, for the multiple cases of WALLHACK (if you weren't aware, you can slide through the corners of the room, i think in every level here)
