Thank you for your feedback!
I tried to pay more attention to the translation this time.
The sound of the tentacles, I intended it to be uncomfortable. And about the eyes, on my devices I had no problem to see them well. While it's true that part of her design was to have dark eyes unlike the rest. (To express more her strange nature).
I wanted to add the characters next to the text box, but you're right that maybe for some people it's more annoying than pleasant. I'll try to investigate if I can make it optional or not for next time.
Again, thanks for your review, and I hope you enjoyed it. ~
