Lag messes up an FC (and don't you dare ask what an FC is).
The layout is made in such a way that it makes your brain confuse left and right arrow keys.
Hostage level is impossible.
You can get pretty far with 1 heavy tank and a gazillion missile, the choppers kill the truck, and the driver is a retard.
I wonder if anyone else got the Linkin Park reference in the impossible badge.....
Also, game is buggy. Touch anything and it sets, I somehow got one of the pieces to touch a pixel of another block and ruined my whole tower.
