Part burrowing theme, part cavern theme is what my entry will be. The character (probably going to be named Jimmy) fell down a dry well. Convieniently, he happened to have a pickax. found a hole in the ground and brought a pickax for an adventure. He starts digging away at the walls of the cavern to see what he will find. I hope to have a game where you can take different approaches. There on one hand is the ability to dig around and see what you find in the world of underground. I also hope to add some building mechanic beyond carving away at the rock so that you can start a little house underground.
