Demo Update v.0.1.2

List of improvements:

• Settings tab in main menu is now divided in sections
• Resolution and window mode options
• Keybinding option
• You can change lines with one button
• Offset master is now saving audio/video offsets during game session

Resolution and keybinding options are being tested now and will be improved in the next patch (because now, for example, you can bind the same key for different commands).
Besides that, tutorial is not reading your custom keys and will always display Z/X buttons.

Next update will be on the next week and will 100% contain a simple saving system for your settings.

P.S.
Eyedol33, I didn't add toggle fullscreen option on F button, because now the game will start in borderless fullscreen, that should resolve your issue.
Drewchompski and skywing, I hope resolution dropdown will resolve your issue too.
plaguetonic themes, I still don't know what causes game to stutter on your PC, but I'll investigate further.
