Hi, I'm not sure if I will release the game on steam, but if some day I do then I will give a steam key for everyone who already bought the game here, for free obviously!
Thank you for taking the time to respond, very happy that you did. I'll be picking up a copy from here today, and it's also really good of you to honour previous purchases too. Best of wishes with your journey as developer, you're doing a great job thus far.
