Python and Pygame are one of the first tools I used to make games on the computer. While I've since come a long way (and realized there are much better tools to work with) I'm impressed with the organization and ingenuity I see in my early programming years. I realize it may sound a little conceited (by no means was the programming perfect, it could have been a whole lot better), but I think it really shows the effort people can put into something when they're passionate about it.
The software is available on my Gitlab: gitlab.com/First-Jon/simple-game and it requires Python, Pygame, and Numpy to run.
