Seems like a lot going on... Cool stuff & nice work
Edit: Just to clarify how to install new skins,
1 - Unzip the archive and copy the full directory Cosmic inside ANA 2 GUI folder at the following location:
WINDOWS Users : C:\ProgramData\Sonic Academy\ANA 2\GUI
MACOS Users : yourmacosHDD/Library/Application Support/Sonic Academy/ANA 2/GUI
2 - Once done, just open an instance of ANA 2 and click the "wheel" icon above 'Menu' to access settings and use the 'SKIN SELECT' drop down menu to see & load your new custom skin.
