Everything is said in the project. INFO ABOUT THE FULL GAME: Though progress has been slow because of many things, the game is still coming along fairly nicely. Still a few levels to go, and some more polish. ABOUT KOS-P: KOS-P has been completely redone, to the point where everything on Scratch shared so far is completely irrelevant. It's also been moved over to Godot! If anyone still cares about this (Or KOS3), I'm happy to give updates whenever asked.
Everything used belongs to their respective owners. Just take the time to listen to this weird collection of songs. Whoever manages to guess all of the references in the song titles will get... nothing, but maybe a good feeling.
