If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Old Templar Vaults are full of treasure! Shoot your Cannon to hit Treasure Bricks. With each hit you'll knock out a Bonus. But just knocking out a Bonus is not enough - it must be caught to be collected! Your goal is to collect as many Bonuses as possible!
Controls: Aiming - move the mouse cursor to adjust the angle and power of shot. Shooting - when you're happy with the shot, just click to fire! Collecting bonuses - move the mouse cursor over falling bonuses to catch them. No need to click! To unlock the next level you have to hit at least all the Primary Treasure Bricks (marked by a pulsing red glow).
