Hi Vitoco.
I'm sorry to hear you were unhappy with the benefits you received as a Patron. It looks like you were a patron in the month of May and cancelled at the end of the same month, so you were a Patron when Build 0.4 was provided on May 4 for 30-day early access. By "fixing old chapters," I assume you mean the reshoot of Chapter 1, which took about a week of development work and was also done in May.
For me as a development team of one person, Build 0.4 was a pretty big update of new content containing Chapters 7 and 8 with roughly 800 images and 2000 lines of dialogue and menu choices. If that was only a "few seconds" for you and was unsatisfying, then it definitely sounds like this isn't the project for you.
I'm sorry it wasn't the right project for you, and I hope you are able to find other content/developers you're more happy with! Best, BBN.
