Is there any way to buy/obtain the source code?
Not that I know of - Super Crate Box source code has only been made available in a Humble Bundle in 2015
Big rip. Thank you though. I love this game so much and want to add more stuff to it even though I have zero development experience.
I don’t know what GameMaker version was used for steam release of SCB, but you could try opening it in UndertaleModTool
