in the beggining it was lika "AHGRRRRRR FACK THIS GAME" but then 30 mins into it you get double jump and everything is fine. Overal a great game, challenging yet lots of fun. It could maybe do without the invicibility when you appear most check points are on safe places and i used the invicibility to go trough a "electric fence" when getting the 9th key
