I'm working on a programming game called "Pragma Twice". As in, playing the game involves programming. I just put up a steam page for it (https://store.steampowered.com/app/3528840/Pragma_Twice/) and have a demo submitted to Valve for review (which should hopefully be approved any day now, since I'm trying to participate in June's NextFest)
This game was originally inspired by the game "Untrusted" (https://github.com/AlexNisnevich/untrusted)
