It's good if you play it with a guide. It's basically a femc version of Monster Girl Quest; the fights are scripted with intended moves to do, so following the script lets you beat it without getting hit. But unlike MGQ, you're not handed the solution, so it wants you to experiment with strategies (and therefore have her lose once or twice, and progress the villain routes by doing that).
Highly recommend it with a guide. Kei is adorable, and she makes me want more JD femcs.
