The completed game on itch will be free c: (which is why it takes us so long to make, it doesn't generate much money)
but we work with a lot of console games for our "day job, pays-the-bills" work, so after the game is complete we might consider re-releasing on console, and that version would cost money. That's very far in the future though, and I don't have a figure for it.
Thank you for your support! :D
