The game is so laggy, I can't even play it. The cursor often either doesn't move at all, moves by itself, or moves extremely jerkily. At least the movement works normally (most of the time).
To all those complaining about level 2 being glitched: it's not. You have to click the "Select Ammo Type" button in the Shop.
Although level six is nigh-impossible for those who use a trackball mouse.
