About this game

NOTE: This is the original Ludum Dare version of Chthonic Brilliance. There is a newer version available here.

You control a small slime who is trying to collect gems in the underground. Dig through blocks to make your way through all 20 levels!

Made in 48 hours (though I started late) for Ludum Dare 48 ("Deeper and deeper").

You can destroy dirt and sand blocks, and push boxes, by selecting them with your mouse. Dirt is not affected by gravity, but sand is. Collect all the small gems in the level first, and then collect the large gem.
