Chain of Challenges, episode 27.
Have you ever wanted to make your own pixel art farming simulator? This challenge could be the closest thing.
Build a mockup of a game about a farm, greenhouse, garden, arboretum, forest nursery, etc. in a top down projection, using 32x32 tiles on a 512x320 canvas. You can fill it all with tiles or you can add an UI, but keep the main game screen showing full tiles (for example 9x9 tiles and UI around it).
You have to use the Farmland-20 palette by Eclipse89.
