Another idea. Our hero is on an island vacation and the volcano unexpectedly erupts. You must fly to different areas of the island to rescue the stranded islanders and tourists. Deliver the most survivors to floating collection bins to earn a spot on the Leaderboard.
This would be a timed game with timers to change safe areas to lava at certain intervals. Save those closest to the top first... Once the time runs out, the lava will cover the island.
Maybe 10 minutes with 1 minute intervals
Combo time: The airplane explodes because it was hit by a rock from the erupting volcano!
Mind Blown!!!
