RUSH is a puzzle game made by the creators of Toki Tori, a game I also recommend.
-Soundtrack, like holy crap, soundtrack. It's the best soundtrack EVER. Period. Not joking, there are few soundtracks that compare to this one.
-Graphics, They are nice, and run smooth without slowing down old computers.
-Low requirements, you could have a computer from 1982 and still run this. (Ok, ok, fine. 1983.)
-The gameplay, it's nice and has an original feel unlike most puzzle games which revolve around pushing little blocks around.
-Difficulty. I'm an achievement hunter, I enjoy a good challenge, but this is H A R D. I have played for multiple hours and the difficulty, oh man. There is this one easy level I just flat out can't beat.
All in all, good game.
