This game's biggest flaw was how simple it was. Besides that, it was a bit hard to find anything that was really THAT bad. I think the best thing about this is how you don't have to learn a lot of hard instructions. It's weird, because simplicity can be both good and bad for something at the same time. The music was alright.
It was a bit hard to really be interested in it. It wasn't that well detailed or anything. I do get the notion that it probably wasn't supposed to be that elaborate. I think you need to work with shading and I don't know if there are differences between the balls. It just got too repetetive.
