Im guessing the steam version is updated as well? Keep up the great work!
Yes! You'll need to switch to the beta branch on Steam.
EDIT: The process for selecting the beta branch has changed since some of the online guides have been published.
1. In your Steam Library, right-click on Oh So Hero!, and select Properties...
2. Select Game Versions & Betas, and then select the beta branch.
Thanks for enjoying the game!
