This might not be online forever, and it will likely receive updates in the future, but for now, I have a little server with a game I made at pokedraw.today
This is a game is just a little whiteboard and a target pokémon. Insert your name, and then you get 30 seconds to draw the Pokémon from memory. After the time is up, the drawing is automatically sent to the server.
All drawings are then saved and are visible at pokedraw.today/drawings/.
I’ve also added a little cron job to change the pokemon to be drawn every day, so I hope you check it out every so often!
