V2 Update: Fixed app crashing on launch on Android 10+. 
NOTE: THE GAME IS BEST PLAYED WITH A BLUETOOTH CONTROLLER

This is the Extra Version of Rainbow Islands. The gameplay is the same as Rainbow Islands except the stages' enemies and bosses appear in a different order.

The game is set on a chain of ten islands, each one with a different theme. Each island provides four rounds of game-play, and once these are complete the player moves to the next island in the chain. In each round the player must get to the top before the sea level rises and kills them. The islands get progressively more difficult, with enemies moving much faster on the later ones. These are depicted on a map screen before the start of each island.

Players can release rainbows that act as weapons, makeshift platforms, and item collectors. Slinging rainbows damages any enemies and acquires any items that the rainbows come in contact with. When jumped upon, they fall down, beating any enemies below them, and releasing a damage field above them. Collecting power-ups increases the player's speed, the speed of the rainbows and how many are spawned. If players take too long in a level, water will start to rise up from the bottom of the stage, and will kill the player character if it rises above his head.

A classic platform game. This is the Extra Version of Rainbow Islands.
