I let people in the Discord chat know about this a little while ago, but it's probably worth sharing here where more people might see it... I have released the source code to a bunch of Hamumu games! You can visit this folder
to grab them, but actually your better bet at this point would be to visit SpaceManiac's HamSandwich Github
where SpaceManiac has set up a repository where a bunch of people are working on updates and weirdness for these games.
And don't forget to stop in the Discord chat
where you can hear a lot more about it from the people who are actually doing stuff with the games. Where this will lead, I do not know, but that's where you can find out as it happens!
