can I make a C64-Game?
You can do, but as long as you port it to a browser or windows exe file, so we can play it without having to download any extra software.
I hope you do! I love C64!
c64 is not allowed! it must run on windows or in the browser
then make a game that looks and sounds like it was made on C64 that runs on Windows or in a browser, like I tried to do with this one: https://kalimanusthewanderer.itch.io/class-clown
