Play Outhold on-the-go with the mobile version available as of today!
The game features no in-app purchases or ads. It costs $3.99 and offers the same content as the Steam version (including the new content update), but customized to fit great on phones in portrait mode.
Known iOS Issue
Update: The issue should be fixed now.
The iOS version has a bug with the "Play Again" button, you will have to always go back to the upgrade screen between runs for now. A bug fix for this is currently awaiting an expedited review and should hopefully go live later today.
