I’m not entirely sure how itch works—I know, it’s ironic, lol. But if you buy version V0.11 right now, you should normally get V0.11.1, which includes all the content released to date.
When the Steam version comes out, I’ll adjust the pricing structure so you’ll need Episode 1 and then purchase additional episodes for a small price. But don’t worry, you won’t need to rebuy everything. We’ll talk more about it when the time comes!
