Actually really enjoyed this xD Im partial to a bit of minecraft parkour so i didnt find myself getting to annoyed but ran well. However, the PC I played on didnt give the game very good FPS. Im not sure if that was my PC or the game itself. Probably my trashpot of a computer.
There were a couple of glitches where you would end up running along the floor without respawning, and when you hit certain blocks you would get reset and there was even a point where the game view just left the player, the game stopped and you could see the whole course xD
But overall, simple but fun!
