I've just released a pixel map generator tool that allows you to generate and edit your own pixel maps for use in your own games or other projects. I originally worked on this project for a creative coding unit in 2021. I forgot about it for a while but rediscovered it recently and think it's still quite good, so I decided to release it here. Feel free to check it out here: https://mark-auman.itch.io/mark-aumans-pixel-map-generator
I currently don't have any plans to develop it any further, but if you run into any bugs or have suggestions for improvements or additional features, comment them down below and I may add them in the future.
