My kids want another bird that is angry...but wants them to fight each other too. That sounds like disrespect for one of my favorite games actually. And they did mention that they want to visit the 'snow city' to throw snow balls at each other. So I guess it naturally converged into this snowball hurling game!
Lots of fun for 2 players shooting snowballs and other weapons at each other.
You are allowed to build a wall first in defence! Then click your half of the screen to throw snow balls.
