Out of all the games I own it is most similar to "Rising World" and before you say "who dat?" well that's the point, it's only really comparable to obscure titles and therefore relative to the popular survival games it is unique and therefore popular.

Best thing you could do is find some let's play videos on youtube. I don't know why devs don't release demo versions of games like this. Have the demo end once you defeat 1st boss.
