Sorta boring.
The game was fun at first, but I found it all to be really easy. Which means a lot from me because I usually find all games somewhat difficult. (And no, I don't have a mental disease.) The only hard part, in my opinion, was the changing of water to air. But eventually I figured out that if you look at the tail end of the orb, then you can see what speed it is really going, and slow down before you go into the air. Other than that though, I was able to avoid all the walls very easily. The music was good, it kept this whole futuristic type of feeling throughout the whole game. I know it would be hard to fit in, but if possible a difficulty setting would be a good touch to make it a lot more exciting and enjoyable. That would give you my 10/10.
