I loved the intro but didn't liked the art style and the sounds of the game. Sometime the sound missed and double jump didn't worked. The first 4 games are a walk in the park and then the last level is just a walk in Hell, no balance at all.
So i decide to give 2.5 stars. Was a OK game, you made a good intro and a decent platform game despite some technical problems.
PS. I hated the boss fights and the last world. SO FRUSTRATING!
