How did you calculate such an outrageous price？

I know there's an opacity feature to help make the text more readable, but it doesn't help when half of the (English) text is outside of the area of the text window that's a solid colour, causing the text to blend into the background image's colours rather than standing out against the solid colour background!...

what is the email to contact the devs and how many chapters/hours is the game?
