I really do love this game! It's mostly because of how simple it is. At the same time, it isn't stupid. The Z at the end was lame, but fit the tone. I appreciate the sounds and everything. I was surprised at how its difficulty changed. I felt like it really didn't get any harder. The proportions stayed the same.
Well, okay, the first one was really easy. While not well detailed, it's really good. I'm kind of sad to see the little balls disappear. I don't think I learned much about atoms here. At least it's trying to be educational.
