Pastel Island (Japan, prototype)

Pastel Island is a maze game from 1993 where, by the time-honoured tradition, you are tasked with collecting all the points items (this time they're hearts) in a stage, before going to the next stage and doing it there, and so on. Stars are one of a few random power-ups that can appear when you destroy one of the destructible items littered around each stage, and when you kill an enemy. The stars, when collected, multiply the value of the hearts for a limited time. If you collect a star while one's already active, the multiplier increases by one. The other main scoring element is the selection of end-of-stage bonuses available.
