Man, the star clicking. It's always the star clicking.
This one's got Akina, right, and she's just standing there in her little outfit and the first thing you notice is the UI is basically a game of hot and cold from 2006. You click her clothes off piece by piece but not in any logical way. It's like, click the shoulder, then the knee, then suddenly her bra is gone. There's no rhythm to it, just hunting for those little flashing stars like you're playing a Flash game on Newgrounds while your parents are out. And the whole time she's got this expression like she's waiting for a bus. That blank, thousand yard stare. I wish the dev had spent another week just on the eyes, you know? Make them follow the cursor or something. But that's not happening.
