Stolen game.
This is a flash remake of a polish game SOLDAT. Even some sounds are ripped (sound of dying guy is what I noticed, can't say of more). You are getting credit for this... you could have at least written about the rip.
Whatever. As for flash part... well... can't say a bad thing. Good CT music, smileys look kinda cool, many game modes - excellent! But the fact that you stole it... well... i'll give some stars for the effort that you've put into creating this (being a programmer, I know this must've taken a LOT of time).
