Thank you so much for your feedback!
Currently, I don’t have plans to release the latest version of the game as a paid option on itch.io. However, the most recent update (0.2.2) will be available here for free once the next update (0.2.3) is released on Patreon and SubscribeStar.
You’re absolutely right — I’m planning to add alternative storylines and multiple endings to the game.
