Ain’t got much time this weekend, so I’m going with the smallest fun thing I can think of: you are a buried seedling, trying to reach bits of food underground so you can blossom at the surface. Got the basic mechanics up and running this evening—there’s a time limit roughly based on the shortest distance between the food-bits, and you have to get all of them then get to the surface before that time runs out.
Lots more work to do tomorrow, especially on the art—haven’t figured out a style there yet, but I’ll see what I can come up with in the morning.
