I've been looking forward to trying this one, and wasn't disappointed! The overall quality of this visual novel is really high... I appreciate the details, down to the hand-drawn menus and buttons. You often put your art down, and while I won't pretend there isn't room for improvement, I think this may be some of your best work yet. The overall aesthetic works great... it has a coherence and style that really works in this format. It's been fine in 3D, but as a fully 2D work with drawn backgrounds it clicks. The posing and action is dynamic, which helps sell some of the bigger moments. Also, the animations are cool and add a lot.
The SFX and music may be sourced, but all are used to great effect and really enhance the experience.
If I had to pick one thing I'd like to see improved, I guess it would be the story. Nothing in there is bad, it just feels really fast. Maybe a little more time to get to know the main character and get into their headspace. A little more build up and reaction from the characters around them. Again, I felt like everything that made it in was good, I'd just like to see a bit more of it.
It's a problem I've run into plenty of times with my jam games, so I know how that goes... and I know you were limited in your time for this one. So take this less as a major criticism, and more that I liked it and wanted more!
Also, darn it! I drew Sakura BEFORE playing this and now I like her new haircut. I'm going to have update that...
PS: Forgot to mention that I played the web build. Seemed fine as far as I could tell, no issues. When I clicked it and it popped up the webplayer, it did display the working title though. Not sure if that matters to you.
