Possible Steam Release

I'm thinking of releasing this on Steam when its finished, anyone who played the unfinished and free version that which will be continued to be published here, will be allowed to get a free version of the final release if I am able to release this on Steam, if not it'll remain free, it all depends on if Steam allows Twine games to be published and if I choose to make the final version pay to play, there is a 99% chance that I won't and only a 1% chance that I will, I just decided to inform the public, early on so its not considered a out of the blue choice to switch it from free to play to pay to play, even though the chances of me deciding to make it pay to play being a mere 1% chance.
