I enjoyed the game. Also Dev, English is not the problem. For me atleast. ending feels a bit rushed. But after reading your comments in the end I can understand.
I agree, English translation, word usage wasn't an issue for me either. I have played games that were much worse, language-wise.
It may be that you only skirted the "incest" concept with the whole "raised you like a son" thing. I also know that Patreon has pretty strict rules; however, I have found many, many devs on there that do not follow them ... you may want to consider a work-around that some have used ... a patch to remake the relationships in the game ...
As to the game as a whole, I did enjoy most aspects of it, the sex scenes didn't look bad, and the story was engaging ... ghost haunting someone to stop her
...
I am curious how you plan to tie up the loose ends, sorry to see the game end, but understand about the whole financial aspect.
