WARNING: If you are not very, very determined, or get easily frustrated and have been known to break things, DO NOT play this game.

It's kinda old now (came out in 2006 i think) game that I've always loved called I Wanna Be the Guy. It's a platformer with mediocre graphics that pays homage to a bunch of classics: Mario, Zelda, Metroid, Street Fighter, Castlevania, Tetris, Megaman, and Ghosts and Goblins (there may be one or two that I'm forgetting). However this is, without a doubt, the hardest platformer out there. It's so sadistic, torturous, and unforgiving and it's funny. I'm not kidding! Give it a try! Oh, and play with the music on. It'll bring back some memories!

Has anyone played this before? Did you beat it? Could you beat it on anything other than medium? Im currently on the 4th boss (of 7) on medium (the lowest difficulty). The difficulties dont change anything except the number of save spots
