I found this to be a fairly enjoyable game. I think its biggest weakness was how it didn't have that much detail. I can of course tell that this wasn't supposed to have that much detail. I liked how it just had a really optimistic tone to it. I can see how happy the balls are when they are released. Some of the levels are very well designed.
The one level that I can not get past is the eighth one. I like how there are different balls which all serve different purposes. Many games like this do not have variety like that. I do seem to lose time after I set one ball down. Gee, this sounds dirty.
