Okay, played a bit and took some screenshots of some issues and stuff I just want to mention.
I think you meant to put "whispers" instead of "subheading" Also, I think the dialog box needs some work. If you look where it says "Q Save and Q Load" you can see weird icons there. The character's names are a bit big too. You should see how it looks when Marco and Sandra are singing together lol

It says "her" when it should be "him" and "hug it" should be "hug him"

Weird icons after "Valentina and Martina"

It says "He" instead of "She"

It doesn't say "full screen" "quit" or "disable" in English and if you look where it says "Auto Forward Time" there's a weird icon again.

The text is too big here. Maybe you can put the character's names on top and not where you have it. I know you probably wanted to do something different but just saying.

It says "He" instead of "She" This happens a couple times.

It's showing the wrong person talking.

Some text is still in another language, like this. Saying "Milan" Especially when the game starts.

Should be "Give Her A Kiss" and "Better Not"

Sorry for all these screenshots. I know there are a few more mistakes here and there but I didn't want to make a super long post with too many. I still haven't finished playing either lol. Hopefully these screenshots will help you out a bit though. There are also weird icons and such when you are on the save menu. Look at the bottom where the numbers are, and you'll see what I mean.
