About a month ago I made a monochrome pixel editor on my #playdate, so that it's convenient for me to make #pokemon sprites for #picodex in #pico8. (Hashtags done!)
The left side is the editor. Middle is preview, and right is a reference picture from Pokemon Crystal.
Originally the program took up the whole screen, but my toddler dropped my playdate on the ground and the top half of the screen started flickering, so I modified the editor to only use the bottom half :D.
Suprisingly, making sprites with this editor is much easier than making them with pico-8. Because there are only two colors, "a" toggles the current pixel. "b"+dpad moves all pixels. And "b"+crank switches to a different Pokemon.
After a month of spriting with the playdate, I'm about 40% done. 100 down and 150 left.
