It's great when it comes the idea of of the game, it's goal, and the music, oh my the music is sublime. Starting out the game, it took me to seconds to figure out what to do, nothing needed to be explained, the name gave me all the hints I needed. But I do have problems with it. First, it looks dull, the sad brown and grey levels contrast with the elements with bright colours, like the enemies or the reversing power up. Second, it gets too difficult to quickly. Levels one and two are nearly perfect, save for the slanted platform killing you (seriously, do you expect anyone to figure that out without dying first?) and second, only ten lives. If you start level and take a minute to survey your surroundings, you die, if you jump in either direction, you die, and when you lose all your lives, its just back to the title, I first thought it was a glitch. Ultimately, the game expects a lot from you from the get go, and it doesn't do a good job of motivating you from the start to keep playing. Add some excitement to the art, and keep the challenge, but make it more fair, according to players mistakes, not some random bull&*$! you can't avoid the first time.
2 and a half stars for a clearly thought out game, but not entirely.
