This was something that bugged me as well, but didn't say anything because I thought it was intended, I don't know.
Just played the spin off and between that and the small size of the font, also found it to be really hard to read.

Some characters get straight up cut, and there had messages I legit couldn't read...
Other games with similar themes, like Netorase Phone and NTR Phone, have messages/text double the height of the one used here. Maybe using bigger font size would make it so the pixels don't get chopped up?
Also, there should be some mechanic to rollback or something to go to a previous choice.
It's not ideal to get different endings by reseting the chat everytime...
Other than that, keep up with the good work!
Your artstyle is really cool, and Felicia is very hot. Hahaha
Looking forward for the next updates!
