Some of them are not even remotely clever, a couple flat out don't even make sense... i love the concept, but the execution of this game leaves it less than desirable. The ending is a huge let down. I'm sure a spin off with everyone's comments in mind will yield MUCH better results :)
If you are going to take the time programming something like this, however simple it may be, why not make it look a little cleaner? That maze is shit, sorry dude
