I just released a point-and-click adventure game called Transfer Point. It was made almost entirely live on Twitch using World Builder and MacPaint. World Builder is a program from 1986, created by William C. Appleton for the original Macintosh. I'm currently working on a Playdate version of the game.
Some games I particularly enjoyed.
Just some Mac games that looked interesting. Their inclusion here is not necessarily a recommendation! These should all run in Mac OS 9 or earlier.
