Putting a price tag on the original is understandable. Not posting any updates for 6 months, whatever, your patreon subs probably aren't happy but you aren't under any obligation to continue regularly make posts and release new updates. Then you double dip and put the remake of an unfinished game on different page, so anyone who supported it previously loses out, why not? I don't know man.
For the past 6-8 months, this new version of the game has been in development. The page for the Ren'Py version of the game is still there for the people who prefer a more linear Visual Novel style game. This is essentially a complete remake of the entire game, with way more features, more content and faster updates in the future.
