HOLY MOLY this VN is impressive! The soundtrack herevery is GORGEOUS.
I really can't put into words how much i love the sounds youve chosen. <3 <3
As someone who is working with ren.py currently the UI and backgrounds are fantastic. The backgrounds have a consistent style and they are visually interesting as they are. (A lot of devs use a very basic filter effect and poorly implement it. These effects are so well done here. They wouldn't look out of place in a big budget game.)
Overall I really like the story and the direction its going. The writing was good and your character sprites are very very nice looking. I've finished the story content you've written so far and I've got so many questions... I want to know more haha.
The font you've chosen for the dialogue screen was a little difficult to read in some of the longer lines. I really appreciate it's stylistic effect, and it definitely makes your VN stand out from others. Some of the longer sentences or paragraphs could probably benefit from being broken up into seperate lines. This makes it easier to digest.
I really hope you get the attention you deserve for this demo! I'm really impressed. Fingers crossed you'll think about releasing an update soon! :)
