it was okay
the game was OK, after a the handgun there was just no need to use anything else. basically it was just too easy. there are also some minor things like the hit-boxes, would be nice if hits to the body actually registered/did less damage, instead of just showing up as a headshot, also the ability to manually reload, because there are times when no enemies come for about 3 seconds, but you have half a clip of ammo, so by the time you empty your clip into the air, the enemies are coming already, or if you wait, you still dont have enough ammo.
Also, the laser doesnt reach the end of the screen, it stops about 1 fifth short, which got really annoying.
but overall it was okay, but ( like Virgil said) it wasnt anything new or interesting.
