Is it stolen?
About the game: needs ammo counters, a clearer indication of what you are supposed to do, and maybe some sort of reticule. A good game, just needs a little more.
Perhaps consider adding ammo so that the play cannot just constantly click and move the mouse around.
As for the game, its not bad, it just could use a little more polish. The two stages is certainly a start... good game, keep working on it, 3/5
around level 5 I realized I agree with the title: I hate ice levels. 3/5. could be much better with tighter controls(WALL JUMP!!)/less annoying ice physics
not at all bad.
one bug you will want to fix is that if you shoot the second guys head after shooting the third guys head, the third guy will become alive again.
but as for the game, you might consider taking out the gun that follows the mouse: its alright, but it would be difficult to get that to look good; I would just have the scope (i.e. the game Tactical Assassin).
Keep up the good work
There are hints of a good game under here, but, this certainly needs a lot of improvement. Graphics definitely need upgrading, but more important would be text (ie instructions, class discriptions, etc). Right now its hard to see the game as it is because the framework is unfinished.
