I did see a few low-poly, very PS1 or N64-looking indies recently, even going as far as mimicking the weird texture wobbling from the PS1.

But Penny’s big breakaway is not really low-poly, or something that looks like 5th gen/PS1. Not graphically anyway.

Though it’s mechanically rather retro, with the focus on move combos, scoring and speedrunning. It’s almost more of a linear kind of skate or jet set radio-like game than a platformer.
