Wow
Just. Wow. The only thing i can even slightly harp on you guys about was the dwindling fps near the end that made aiming with the mouse a tad more challenging.
The last few levels were just starting to be a giant mind fuck, with dodging turrets and dropping boxes and stuff. But still. Wow.
And maybe just a little more Wow.
For those who need help on #9, just remember that you cannot fall to your death in this game. Even if you were, oh, say, falling into a bottomless pit.
