It's a fun game. It's not a new sort of game but it's still nice. I would suggest implementing controls for 'wasd' as well. It'd also be nice if you would clarify what the upgrades really do. They don't seem very significant to me. But overall, it's pretty good. Nice art too :D
One thing I found to be fairly impossible is the fact that with all the nukes wouldn't the other trucks be destroyed? Oh well, who cares, I'VE GOTTA SQUID LAUNCHER (This makes my argument fairly invalid)
This was a wonderful game. When you realize that all the odd rooms and such aren't actually like that it makes you feel good inside. It's all a trick on your mind even though it's what is inside Kathryn's mind. I adore this game and it most definitely deserves a 5/5
It's things like this that are why I am switching to Unity. Fixed.
