Hardcore Gaming 101 - Psychic 5
On the surface, Psychic 5 seems to be a pretty typical Arcade Platformer for its time. As soon as you put in your first quarter, you're taken to a screen that shows five characters, each with their own parameters - some jump higher, some hover longer, some are stronger, etc.
Psychic 5 / Esper Bōkentai
A pair of 1987 games by NMK starring a group of kids with different abilities and extremely floaty moon jump physics.
