Moonman is a really great looking new Terraria-esque procedurally-generated adventure game that looks too good not to share. They are on Kickstarter right now looking to raise 35K and if you want to get in on it, you should!

"In a strange, nocturnal world a moonman is summoned by an ancient mollusc. It sends him to the seven farthest corners of the land to search for fallen moon fragments -- that will power a great star-machine.

Explore a strange and vibrant world, harvest resources from the environment, craft and trade items, and have odd encounters. Each new game generates a unique world to explore.

You play as a happy green moonman whose quest is to search for fragments of moons that are scattered around the world. The fragments may have been hidden in caves or tombs, ingested by large creatures, or hoarded by agoraphobic hermits. The game features:"

Moonman has been in development for over 2 years and you can read about it's progress thus far on TIGSource. The developers of Moonman are aiming for a mid 2015 release on PC and then later port it to Mac and Linux.
