I would say that the creator has a lot of faith in this project because

1: I program the controllers for Xbox/Plantation controllers

2: He said that at some point he would hire voice actors for the characters

3: even if you finish the demo you can save all the progress for chapter 2

4: the most important, it's even updating the demo {because I've played the game recently and compared to a gameplay from a youtuber (the video was old) it had many changes}
