Bunny Must Die/YMMV


 * Anticlimax Boss: All of the bosses you're fought throughout the game are easily steamrolled by Chelsea.
 * Demonic Spiders: The giant walking turrets. They shoot giant beams that cause huge amounts of damage, take an obscene amount of damage to kill (while throwing up a Beehive Barrier every time you attack to keep you from just spamming attacks) and love to take up residence in narrow passageways where it's a major pain to get by them. Fortunately, the Spike Hammer kills them in one hit.
 * The floating, rotating turrets, which have even more health and are a major pain to dodge.
 * Game Breaker: The ladder. So many boss fights can be easily ended by either using the ladder to dodge projectiles vertically (plus you get rapid-fire abilities while you're on it) or just bashing them in the face with it until they die. And the fact that it stays on screen even if you switch to a different item makes it even easier to abuse.
 * Goddamn Bats: The local Goomba analogue is a flying jack o' lantern which likes to drop fireballs on you. If you get too many in one spot (or have bad timing with just one), they can be a major pain in the ass. Some of the bosses are ascended pumpkins, and they're just as difficult to deal with.
