This game is a great game but I feel that having to get all of the power orbs is a bit tedious. I mean, you could make it so that you only need ten of them but put like 15 in the game or you could make them optional entirely. Like, you can find them by exploring and you could use them for some extra speed or make your light bigger in the dark tunnel. I would also add something that allows you to stay at the end of the area once you collect the part so that you can find the orb that is usually hidden after the part. Another thing is to put a reset button that kills you and brings you back to the big robot. Other than that, this is a great game and you should keep up the good work.
