Blast your way through 3 levels. Everything except for a few graphics and sounds by me.
Left & Right - Move left and right.
Shift - Jump
Ctrl - Shoot
If you see any suspicious looking elves under any ramps it's probably best to surprise them between their shots.
Watch out for yellow presents. Originally terrorists tried to take down Santa's sled with them. They started this new screening process for bombs though that involved molestation, and the terrorists just decided to kill people on the ground with them instead.
Shoot the gun fast. You'll have to.
This game is actually possible to beat(I've done it multiple times). If you can't get over the first jump let me explain how you do it. You press the right arrow key and when you get to the very top of the triangular platform you jump (while you're still pressing right). You have a little leeway because you can still jump until the wheel is completely off the platform.
The last boss is a giant ass that shits at you.
