Trust me, even if the story has its dumb/hypocritical moments (the blackmailing the blackmailer scenes come to mind, either you use his mom and it's basically rape/taking advantage of a woman or you blackmail him over perving on his mom... when literally the scene before you can grope yours while she's asleep in bed, and the whole purity group thing is debatable), the ending is not rushed at all.
I wanted to see the new addition to the harem route which involved stuff from the middle of the game and I didn't have a save so I started a new save and was able to fast forward/skip most scenes... it still took me maybe 30 minutes to an hour to get to the ending even with that much being skipped. This is a massive story and while I doubt I'll ever go through the trouble to play non-harem endings, if you like incest and preg content this is basically mandatory, especially since (aside from general 'porn game' stuff like said harem and doing a girl you just met) the main character is not a bad guy.
Hell, the "ending"? The main gameplay you play about 35'ish days with variable differences in length, and then because of possible preg content it skips a hundred days, and from there you still play another 5 days with you still interacting with everyone, and on the final days it's a wedding that is built up, done, you dance afterwards, and then sex with wives before going into an epilogue of basically every named character aside from like... 3 (instructors/shopkeeper and the concert).
Don't look at the jump from .23 to 1.0 as "oh wow they fucking skipped 77 updates wtf", but more as they had 23 updates, finished the game in that time, and then decided to wrap things up and call this final update 1.0.
