Really love all the models for this game, especially Shiori and Raden, excellent job!
And its nice to see Raden get some love in a game, never mind one that's so close to her personally, that's awesome!
I think most of everything I had to comment on has already been covered, but one thing that got me was that in the tutorial, it sounded like you would have more time to plot out the route Raden would take, but then it turns out that you can only see the next exhibit she's going to, which led me to panick and end up with the worst score on the first level, since there was no real time to prep or learn the exhibits, since you can't view the model for exhibits that aren't active. But after the first level there, you get the gist of exhibits for the most part, and its easier to come back out swinging in the next levels.
Can definitely feel the love in this game, with all the small touches in the flavor text, and the couple of exhibits that use voice clips from the girls.
Unique idea that is pretty well executed, great job from the team!
