A generally decent platformer, with good music and nice artwork. It didn't give me enough to keep playing, but I haven't seen much wrong with it except the collisions aren't always perfect (which is hard to do well in flash or any other program).
Also, what is "A nice platformer game for those who doesn't know how to spend their free time." supposed to mean? All I can read out of it a passive-aggressive reference to the players. Which is rather out of place.
