Hey Rainbow! You should be able to pay the remaining difference for additional content on itchio games at any time. Future installments and in-game Events will be Patreon exclusive until final release. Chapter One will be replacing the outdated Demo, so depending how much you previously donated, you will have access to the uncensored Chapter One when we release tomorrow!
Thanks so much for being interested in Faulty Apprentice! If you have anymore question let me know =D
