Rainbow Islands: The Story of Bubble Bobble 2

Rainbow Islands is a vertical-scrolling platformer where you ascend multi-tiered stages by creating rainbow bridges. You play as Bubby or Bobby, firing arcs of color that form solid platforms beneath your feet—walk on them, trap enemies under them, or collapse them to crush foes below. Each island scrolls upward as water rises from the bottom, forcing constant movement. Collecting gems and mirrors across ten islands leads to a confrontation with the Boss of Shadow, who's transformed the locals into Bubble Dragons. The rainbow mechanic doubles as offense and navigation: you're building your own route while clearing threats. Stages get dense with enemies and require quick spatial planning. This sequel to Bubble Bobble trades single-screen arenas for vertical gauntlets.
