video game designer here; feel free to adapt anything I’ve made! https://pancelor.itch.io/
suggestions of things I think are most adaptable:
- remains - explore some ruins, try to make a friend
- escalator world! - ride an escalator
- mothbear - a simple roguelike
- ocelot safari - explore a jungle, try to prevent the ocelots from stealing your tools
I’ve made one TTRPG as well called cryptkeeper, which should be adaptable into some sort of roguelike. It’s in the Palestinian Aid bundle; if the community copies are gone DM me and I can send you a copy
