Do you have 'Fixing broken English' on your To-Do-List?
Like do you have some plan for it? Like when/how you would do it?
I'd rate your English 3/5. It's all understandable and it's not so wrong that it's comedic or cringe.
Almost all of your mistakes can be easily forgiven. All except: "Me either".
"I liked it" "Me either". It's supposed to be "Me too"
"I don't like him" "I don't either" is correct, i pulled that one from goggle though.
"Either" isn't used in positive agreement, only in negative one and as i'm aware of relatively rarely. I guess it's a 'if it sounds right we'll allow it' case.
Also the most common use for either is in 'or' sentences, example: "You either like tits, or ass"
Don't get discouraged by my critique though. I like your game so far, and i didn't even get to the h-scenes, which look very nice in the previews i must say.
To wrap up i'll give a short positive review: Good UI, interesting story, good character design, good environments and everything gameplay wise works well.
