I've been working on a port of Pokemon Crystal for a specific ESP32 dev board with a round amoled screen.
The goal was to have a basic pokemon themed tamagotchi clone with step counting that motivated me to walk more. It snowballed into a full fledged rust port of the whole game, with a completely redesigned UI meant for round screens and touch controls. It's got bluetooth and wifi trading, autosave, contextual action buttons, etc.
The most experimental and interesting feature is an auto play mode, which keeps the game advancing while you walk in real life, letting you take over at any time and keeping a log of any interesting event along the way.
Not launched yet, but I have a very preliminar landing page for it here:
