It’s not E ink, it’s a Sharp Memory LCD https://sharpdevices.com/memory-lcd/

Memory LCDs have fast refresh rates while also being persistent like E ink. They’re also more expensive.

Exactly, they're not asking how the playdate works with an eInk screen (because it doesn't have one). They're asking how colesantiago expects to use a game console with a 5hz screen.
It plays the following games

- Crossword

- Chess

they aren't really bistable like epaper; the playdate display requires 50 microwatts to maintain the display. when i unplug mine from the breadboard it retains its image for about 30 seconds before fading just on the screen capacitance

a broken epaper screen, by contrast, retains its image for at least several years
