The new Stories of Bethem: Full Moon update that includes WASD mode is now available on Steam.
The new update fixes some bugs and improves the compatibility with some devices. But the main new features are the WASD keyboard mode and the Steam overlay now fixed on Mac OS X.
How to change the keyboard mode
Change the keyboard mode on the Config option of the main screen. You must disconnect the gamepad to enable the mode changing.
Note: We found a new bug if you play using WASD with a gamepad connected. Disconnect your gamepad if you play with the keyboard. It will be fixed in the next update.
What's next?
We're working to include Steam Trading Cards as soon as possible. A new hidden dungeon will be available in the game when they are ready too. Stay tuned!
