My game isn't very screenshot friendly since it's just an ASCII endless runner that takes place on the moon, but here's a screenshot of a function I wrote to play note sequences/sound effects during the game. I'm using Vim since it's my primary editor both at work and for side projects, and I've configured it a lot over the years to be more IDE-like.
The game is almost finished now and is only ~4.5 kilobytes (2.5 kb zipped)! I'll probably put the project up on my Github as well once the jam is done.
