music is good, the controls are fine, and the level design is not the best but it's kinda fine. Some of the cons:
-Level select don't work it seems, at least for me
-Wish more creative levels or new obstacles because sometimes is the same after you learn how to dodge the spikes
-game lag sometimes
-Plataform waiting in sometimes can ruin the experience, i almost did get bored by this
-I can't see the level now because i can't go to the levels belows 30, but i remember there was a level with 2 spikes and the ceilling too close and had a hole, it's hard to jump that, if i remember i only get through because i did land on the edge of the spike and it didn't get hurt
