Your goal in Cannon Crasha is simple: Destroy the castle on the right side of the screen while protecting the castle on the left side of the screen. There's a relatively disposable story that is designed to push you on, destroying castles and leaving rubble in your wake, but in the end it's Crasha's fantastic medieval combat and old-school aesthetic that will keep you playing.
Equal parts Angry Birds and a lesser known classic, Crush The Castle, Cannon Crasha gives you one weapon to start with: a massive cannon. With each successfully aimed shot, your opponent's castle takes damage until it eventually crumbles. Of course, your computer-controlled adversary returns fire as well, and if you're not careful you could end up on the losing end
