Good concept overall.
The sketchy graphics fit the game perfectly, and the overall feel of the game was actually pretty good.
Some problems though. I think it would be better if we were given an option to launch the Rad Bear, you know, kind of like in Toss the Turtle. Maybe so that he can be shot with more or less power and it determines but not restricts the amount of time Rad Bear will be in the air. Just a suggestion.
