I love almost everything about the demo! The art, the music, atmosphere, and especially the plot and 3D graphics! Erika also seems like a fantastic MC and I'm curious to see how her relationships with the other characters will unfold.
One thing I had a bit of trouble with was the settings menu. Although I set the text speed to max, the text still appeared very slowly on my screen. I also had to click multiple times on the setting adjustment bars and save and load buttons to save or load my game because it didn't register during the first click.
Otherwise, this seems like a great game and I'm impatient to play more of it! Really looking forward to the final product and wish your team all the best in its making!
