No. You shouldn't. The game is not receiving any updates for 1 year, it is buggy, unbalanced and you should not support it. There is a plethora of better games on steam, don't waste your money on this money grabber.

Like many of you, I found the fundamentals of the game solid and ideas intriguing. Thank you Jon for getting it to here largely by yourself!

So I made a mod for myself in order to enjoy the game. After spending many, many hours on it, I figured it makes sense to share it with everyone!...
