So will there be Tailor Tales Plus to buy because I afraid that I wouldn't be able to afford Patreon every month (and I never registered Patreon too), but I really willing to buy the game !
You don't need to be subscribed for every month! Plenty of people just pay for one month to get the goods and then cancel the subscription, which is totally fine :)
Currently Tailor Tales Plus is a Patreon only exclusive. It will be available to purchase on Itch/Steam in the future, but no ETA yet.
