Hi friend, and thanks for the interest! The “Demo” label is because development was originally made in Twine as an HTML game, but after feedback, I moved the game to Ren’Py and put out a “Ren’Py Demo” as a tester to see if people preferred the game this way as opposed to going back to the text-based Twine HTML game.
The feedback was overwhelmingly in support of continuing in Ren’Py, and thus the next full update, in Ren’Py, will be out soon!
