You have tiles that you can throw against a set of assembled ones; if you do it well, many will disappear and you'll be able to advance. Don't let the tiles to reach the ground or you're lost. There's several bonus items, like walls, that appear on the game. Some bonuses cause an immediate action when you hit them, others are latent and have only effect when you hit them with other tiles. | Move the mouse to left/right to aim; click to shoot. |
