Beat 100 levels + Final Boss

100 Levels of the same music? For a moment i felt like i was playing Adventures of Lolo once again. Nice levels design in terms of difficulty but the problem is the graphic part, it is completely lack of any sort of tiles to make the levels look better like in Snow Bros for example. The game is fun but I believe it could have been a master piece with only two additional things: 1. More music and 2. Better graphic design for the levels. I will define this game as "an unpolished gem for NES".
