Greetings.
I appreciate your immense enthusiasm for this game like many other people. To answer your question I'd like to share mrdrnose, own response in regards to steam that he shared beneath the game description.
Q: Will the game be on Steam one day?
A: The game will get in Steam eventually, but the game is still quite unfinished so it will take some time to polish it for Steam release.
I hope this answers your questions!
