Oh man. Looking at my save I haven't played since this first came out! It's such a night and day difference in terms of rendering quality! You can tell a lot of time and effort went into learning the tools being used and to make things that much better.
Can't wait to see future updates, hope they go by smoothly for you!
Since it has been so long since I last played I re-played from the beginning and some minor typos I noticed:
"I must be the only one in town studying on vacation whereas everybody enjoys." enjoys what? It's not said in this or the next bit of text.
"I wanna be Professor once and for all..." -> "I wanna be a Professor once and for all..."
"The house is so quite" -> should be quiet
"Yeap, it's definitely no one here." -> should be there's
"She stores the empty box so it looks like there's still cereal on it but it's just to avoid going to the groceries store" -> should be in, should be grocery
"LIAR! You did saw me!" -> should be see
"It's the first time I see her around" -> should be I have or I've, should be seen
"I say stop staring, you idiot!" -> should be said
"Ok, I stop" -> should be I will or I'll
"... I also touched your boob... and I love it!" -> should be loved
"after my bath I promise I do." -> should be will
"... but first, I'm gonna put some clothes." -> should be put on
"SHORTS no LONG!" -> should be not
"Well, I choose then." -> should be I will or I'll
"What was that? It's that what I'm thinking?" -> should be "What is that? Is that what I'm thinking it is?"
"I think [MC] has it on his pants." -> should be in
"No like [MC], he picks awful movies." -> should be not
"Where he hides it?" -> should be where does
"Yes! There are cereals!" -> should be "Yes! There is cereal!" or there's.
