Wooooaah, I love it!
Everything, from the visuals, the music, how the controls feel, the jump physics, the level design... The overall quality is astounding!
The only thing I can complain about is the fact that the text at the beginning fades away too fast, it's difficult to read it all. But apart from that, it is an excellent game!
Although, I have to ask: is the skip in level 15 intentionnal? Because if so, that's a clever shortcut! ^^
If not... You read nothing, I used 100% pure skill to pass it, nothing to see here!
Excellent job to the team! =D
