Roam an isometric castle of floors, ramps and towers with a gem on every tile. Walk freely in eight directions and sweep up the gems — grab the last one yourself for a big bonus. Gem gobblers race you for them (squash one while it eats), walking trees hunt you, a crystal ball rolls about and, if you dawdle, a bee swarm flies straight through the walls. Jump over ground foes; the wizard hat makes you invincible for a few seconds. Free, no sign-up — play right in your browser.
