I agree with you, and glad I could help lol. I have encountered this kind of thing in a number of games with no warning, and it always ruins what could otherwise be a good game.
I think in this case, however, the dev seems very engaged with feedback, and interested in making a good product. Once he makes an update, I'm going to give it another shot. I'd recommend it if it weren't for this particular scene lol. Another commenter compared it to Artificial Academy, but I think the RPG elements this game has could give it a slight edge on AA as it gets more polished. I have high hopes for it based on Kaito's response to my comment.
