I can't make the promise 100% as there are still a lot of things i'm figuring out - but if it is feasible I'd love to have it here and possibly at a discount since I don't believe itch.io takes as much of a cut as steam (steam is 30% and I don't know if itch takes a cut or not...I need to do some research!).
Thank you for asking and showing interest in my work. :)

You can decide how much of a cut itch takes from your sales.
Steam, however, has a policy where you always have to give the best deal on their platform. So for example, if your game is 50% off on itch, it has to be 50% off on Steam as well.
Good luck on finishing the game, the demo is nicely put together!
