They mention that it's C# and that it's at least 10x the amount of code...

I loved this game! I actually had the Forth package for the C64 also but I never put 2+2 together that the game was made with it.

Glad you dig my old game. Play our demo on Steam!

That's awesome. I will! I was probably around 12-14? when I spent many hours with that game. After that it was DOS and Doom. But I think when I eventually drifted towards the path to being a software engineer I did grasp a lot of the basic concepts faster because I played games like this as a kid. The other path was being a musician of course.

Stacks in ChipWits were very much a result of coding the game in FORTH.
