Im assuming if I the pay for the game now it would only be for version 0.18 since that's the most recent one at the moment of this post or does that mean it will give me access to future versions as well when they release with no extra charge. This would help me know so I do not have one sided expectations, certain games do this while others do not. While I would not mind supporting the game since I absolutely enjoy it, it would be nice to know what to expect for future versions.
