Google the name of the game and you will find a patch if you look at a few sites. That would help you.

It was a nice start. I finished it without the bugs.
The story seems pretty good. I like the girls. The dialogue and writing can improve more. 
Wanted to ask a few things. I really liked how the old man fucked the girls. Will it be possible to fuck the girls roughly as MC? 

Will there be optional swinging/partner swap?
Can we have relationships with multiple girls/ harem?

Bugs happen related to quests. Let's say I just finished a quest once/ or started a quest and if I try to load saves the bugs happed. I think you are saving quest variables globally or something. You need to fix that

Just google the name of the game and a bunch of websites will pop up that have mods. The website called 'f95zone' has most of the things that you need.

Read the comment section and you might find a solution. Google isn't a bad option either.

Looks pretty good.

Looks interesting.
