Play Bio Miracle Bokutte Upa (Japan) [En by Vice v1.0] (~Bio Miracle Baby Upa!!) Online

Bio Miracle Bokutte Upa came out on the Nintendo Entertainment System in 1988, developed and published by Konami. It was part of that era when platformers were experimenting with more unusual concepts, moving beyond the straightforward run and jump formulas.

You control Upa, a baby who attacks enemies by shaking a rattle, which transforms them into bubbles you can then kick across the screen. The goal is to rescue other kidnapped infants by progressing screen by screen through themed worlds. Signature mechanics include growing into a giant version of yourself to break through certain obstacles, and collecting milk bottles to restore health. The pacing is brisk, and the difficulty feels fair but gradually increases. Playing it is cheerful and consistently surprising.
