The plot seems interesting, but the dialogue is infantile at best.
"I think I did well"
"I think you did well"
"I really think I did well"
"I'm sure you did well."
That's not quite verbatim, but it's very close. That's not a translation issue. Other times, phrases are used incorrectly which could be a translation issue. It's really hard to enjoy the story when the characters read as if they're cavemen. There are also too many characters that do not behave in the manner that they are described to behave in, by the character themselves as well as the others.
Some times the dialogue isn't properly synced to the frames. Other times the frame doesn't accurately represent what is being depicted in the dialogue. Or it doesn't accurately represent how the characters would behave in that situation. One example, it makes zero sense for two "shy" female characters to change into skirts to do yoga when one of them is already wearing athletic clothing which is commonly worn to do yoga in.
This game has a lot of potential. It wouldn't take a ton of work. Which makes it even more sad that it's been left in this state.
