Cute game, I like how you designed each of the members with respect to their other genmates and themselves, they all feel very natural together. And I like the combo system with senpai, kouhai, business partners, etc. makes me really want to try to see them all.
Some members feel a little clunky, even when rotated, but that's kinda tough to find a good balance between (I couldn't help but laugh when I started with Lui and then got Kanata which meant I basically insta-lost on round 2, but that's part of the fun) Good work!
