You won't have to purchase it again on Steam unless you wish to support the dev again. He has promised Steam keys to everyone who has already bought the game here on Itch.io.
I do ask that you consider polishing the building system. I can't put my finger on what needs to be done. Anyway, still a cool game with loads of potential.
I really enjoy playing this game and I can't wait till it is finished (Meaning I will pay for this no matter what). I am super hyped up for this. Keep up the AWESOME work!
