We just posted a quick update to 1.0.2 which includes:
- Ability to scroll using arrows
- Option to toggle the old, drag'n'drop controls (experimental! It's possible there might be trivial bugs and visual glitches)
- Sound effects volume now affects the dubbing in outros/intros
- Retrocade logo volume is affected by the music volume
- Display Options have been added where you can more easily toggle between full-screen (it also informs you that you can use F10 for this)
- Added a volume preview when changing sound volume
If by any chance you don't see/get the update immediately try the Verify Integrity of Game Cache option from Local Files tab in game's Properties window.
