Minor controls issues aside, your reward is pure platforming hell. – Impossible Pixel Review

First off, for something of this quality being free is something amazing. The only minor annoyances I have is there are no scaling or placement options for the on-screen buttons. The other being sometimes when you start a level, the jump button does not respond. BUT! You can test the jump button before you start the level & NOT get penalized by the time clock, perfect for you time-attack nazis. Now with the pessimistic crap out of the way, onto the review of one of the greatest games I've ever played on ANY platform. This game is hard. Like, police brutality hard. As of his writing, I've died 808 times, and I'm not even half-way through level 3. You must be VERY meticulous with your timing in order to navigate the various pitfalls, spikes, buzzsaws & other traps you encounter along the way. Highly recommended for the hardest of hardcore gamers. Hats off to 99UP Games for crafting the stuff of legends...
