It's a very unique game, I don't remember if I have seen anything like this on Newgrounds. There are only 2 things that make it a bit unrealistic:
1. An example of the short shorts level and others with the same logic: in reality you would need one more move to do this since you would have to fold both ends of the paper separately, not at the same time;
2. Most of the levels are impossible since you cannot fold a sheet of paper 7 times or more unless you got a hydraulic press for example - or you will use an extremely big sheet of paper, like the Mythbusters did ;-) I just tried to do it with a typical A4 sheet and when trying to fold it for the 7th time it is becoming really difficult.
