That's alright.
Well, the game is pretty cool.
But i have couple of things i didn't like about it.
1-it's too long to be a flash game!?
2-There's nothing new really happen during playing except stronger enemies, and maybe some more weapons and gear.
3-You could've made something more interesting for players to keep playing, like these things written on walls and such.
4-The mini map ain't helpful, and it's disturbing that you find enemies you've killed before show up again when you go back.
I hope you don't take my opinion in a bad way, as i hope if you take what's good for ya from it.
