I’ve released my game Seedship as an Android app!
Seedship is a space exploration/colonisation game based on random events and procedurally-generated text, written in Twine. The app is the same as the web version (johnayliff.com/games/seedship/), but the formatting is improved for mobile.
I will probably do an iOS version at some point, but I’m new to app development, so one thing at a time.
EDIT: The iOS version is out! itunes.apple.com/us/app/seedship/id1340497640
