These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Good Bad Bug — Pink Sweets has this in the form of infinite lives. It's used in order to crank up the rank so high that it makes Mushihime-sama look like a walk in the park. At least that would be the case, if not for the ability to cancel bullets...
Scrappy Weapon: The Rose Hips in Pink Sweets. Shooting enemies with them adds nothing to your score.
The Unfavorite - This game in comparison to other cave games with the main reasons being Yagawa's trademark rank systems, the bugs, and the sheer fact it's nothing like a typical Cave game. (Yagawa games encourage rank control, bombing for score, strategic suicides and avoiding power ups) It shares this distinction with Muchi Muchi Pork, another Yagawa-programmed game of Cave's.
