I wish they made an android port. I love playing text adventures on travels and such.
Can recommend Fabularium as the app / engine (the version on f-droid is newer and better) and then play these with it:
Anchorhead
Coloratura
King of shreds and patches
All of them are free to download from ifdb! Start with this https://ifdb.org/viewgame?id=op0uw1gn1tjqmjt7
Also, everyone (!!!) should try this super awesome horror text puzzle game on browser: https://william-rous.itch.io/type-help
All great horror games, all free, to play on your phone wherever!
