Here's my first Playdate project. It's a simple, chunky, pixel art app. Turn pixels on and off with 🅐. You can save three different drawings from the system menu, and there's a fun animation when erasing one. That's about it.
It's free with the source code on GitHub if you want to check it out.
Not really, though you can always take a screenshot and get it like that

And you can turn off the grid from the system menu if you prefer.
