hey!
if itch says that you own the game don't worry.
after the update, it would be playable
I hope that I'm not saying anything wrong.
I've got the same problem if you scroll down you can see the whole thing on the main page of the game
I'm afraid I'm not a experienced Itch user. I've downloaded an number of VN's. Paid some a little... I do have a number of games in my Library... But I don't know if I actually "own" any games here. :-/
How should I be able to confirm that? :-)
