Cool jump and run with a variety of different obstacles. Unfortunatly the jump button does not always work (played with keyboard), and that was not a cooldown thing, somtimes i could jump tree times in a row, somtimes i pressed the jump key three times and nothing happens (even on flat ground).
Just a personal preference: I dont like pixelised shader on 3D games because it's hard to look at and make me a headache and some times motion sickness.
