It's a very interesting story buildup, and the pacing isn't slow. Although I'm sure he could have enriched and elaborated the content with more teasings and scenes along the way, but I've seen too many devs who get greedy and can't handle it, get burnout, and give up, so I think the current pace isn't bad.
The really sad thing is that the dev gave up on the game due to health issues or something. I don't know exactly if he gave up or handed it over to another dev.
As a huge fan of the INCEST and CORRUPTION genre, it's really a shame, but I want to say thank you dev for this inspirational game.
