I found this to be a decent game. I like how creative it is. It really is the kind of game you would invent for yourself on a rainy day. Granted, I'm an adult, so I wouldn't be a kid like this, but you get the idea. Yeah, it was kind of redundant to see all those rain drops. I would still recommend this.
You did kind of appeal to the inner kid in us. I did notice that mad scientist at one point. The music was fairly good. You really can just stay in one spot and keep on firing. It was interesting how you could test yourself.
