First off, I love the demo and can't wait for the main game! But, I also noticed some minor bugs:
1) In the route where you don't romance either Keith or Tenebris, Tenebris still says "You said you liked me. You won't mind me staying for a bit, do you? I would've bought you something but there was no time." -- obviously I did not say that I liked him.
2) I don't remember if this happens for all the times you click on the option "What kind of sweets?", but Tenebris' sprite disappears for a couple of scenes.
Finally, as much as I like the font on the comment section, it can be a little difficult for me to read, so would it be okay if you changed it?
That's all, thanks for reading! <3
