Nice and complicated
What I liked about this game was that there were just so many things going on. You had no idea when a level was going to end or not. While it was not the most detailed game, it still worked because it had so many things in every level. The music was also really soothing. I find it funny how the first game does not even have the same author listed as the second game! It is pretty fun to just watch the ball float across the screen.
It kind of looks like a soccer ball to me and I don't know why you would use that design. Anyway, it was also cool with how much freedom you had in every level. There was actually quite a variety of places to explore. You had to look at every nook and cranny to get past the level. You could put in more detail and maybe some shading.
