This game is a lot of fun with some friends!
Would you think of possibly making the source code public? I'd love to have a crack at porting this to Mac!
you can find the source code here https://www.spelunkyworld.com/original.html
ps, tell me if you get it onto mac!
There are a few hundred hours worth of changes between the original Spelunky Classic source code and what Spelunky SD is. Perhaps a few dozen less if you take the Humble Bundle version that’s already imported to GM:S.
