This was really cute. A pretty good VN. The visuals were definitely a strong point. I appreciated the characters changing outfits, and the painted backgrounds were very nice (although colors were a bit muddy at times).
I found the writing a little weak at times, often explaining something that was already clear from the visuals (like it being morning). If something can/already is being told visually there usually is no need to write it.
Unfortunately, I also had trouble feeling attached to to the characters, especially Pierce. I think just a little more time spent with them would have helped.
Overall, good job! This is an ambitious project, and it was very well executed! Keep it up!
