I'll make my game in JS with canvas using my own editor (http://webacademico.canoas.ifrs.edu.br/~rcpinto/editor/) and my own micro-engine made in the last few hours (http://webacademico.canoas.ifrs.edu.br/~rcpinto/gameengine.js). I'll be streaming my work from https://www.twitch.tv/rcparts . Good luck everyone!

That's what I have up to this point. You can only dig down, and your dwarf brother, which moves automatically, can dig sideways. Dig as many diamonds as you can and fall to the next room.
