Recently I dug out the source code for a game a friend and myself made in school in 1997. It was amazing to compile it, which it did flawlessly in a DOS/Turbo Pascal emulation. Playing it with my kids was an amazing experience. The code is definitely something I would be embarassed about from a readability/maintenance standpoint today. But on the other hand it can play back video on a 80286 processor :) And I believe everyone understands that you make progress over the years. So I can recommend it, go for it!
My game is available at Github here:
