It's very fun to control, short, but packed with personality, and just a good time. I'd love to try playing this like a speedrunner some time (ignoring all the eggs and just moving as fast as possible).
Only concern of mine is with color. I'm red-green colorblind and Yuyuko's butterflies are difficult for me to see against the blue sky. I ended up giving up on spotting them in her 3rd phase and just kept punching her before she could beat me up.
