Rainbow Islands — About this game
Rainbow Islands gives Bubby a weapon that doubles as a route upward. Shoot a rainbow at an enemy, walk along its arc to reach a higher ledge, or jump onto it to drop it onto creatures below. Pressing jump just before landing also turns a rainbow into a springboard. The adventure rewards more than survival: collecting seven colored diamonds before a world’s boss earns a large diamond. Move steadily, because running out of time brings rising water. Learn to place each rainbow so it helps both your attack and your next climb.
