The game will always be free, with optional support for dev builds that get updated faster. And VIP where you can help shape the game better. Dev builds will let me monetize it for people who want to support or hate waiting, but all content is eventually released on the public free version!
For a limited time now before the game hits early access next year, you can Kofi me to get lifetime access to dev builds/VIP with a one time donation so you won't have to sub in the future if that's something you want.
Dev builds will start rolling out between this month and the next. =w=
