Hey Sl0ter!
We're still figuring out something for those who had paid previously and the plan is to still update the game here. If options for purchasing return to Itch, we'll return to the latest paid/free system that was in place prior to the Itch changes, and if they don't, we'll try something like giving out subscriptions to our Patreon.
We know the entire situation isn't ideal across the board right now, but we appreciate everyone's patience while we sort things and get back on track.
