I love this game, cause it scratches an itch that other games really only gesture at the things it does. 

Minecraft is the best example of this to me, 'cause you can go underground and get resources, but this game is ONLY about exploring caves and mining resources. On top of that, there's a huge wealth of them to find and various bizarre/terrifying enemies to find, not to mention all sorts of environments to explore, so this is really fun.

My only two complaints are that there's a lack of updates, and even more frustrating to me is that there's very few games that are as interesting and intricately made like this.

9.5/10, needs more updates.
