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.
YMMV: Bullet Witch
Best Boss Ever: Tri-Serpent, the final boss, is very epic. He's massive, has a variety of powerful attacks, and can take around a half hour to kill on EASY, yet he never seems cheap.
God Damned Bats: Grudge spirits the annoying ghost's spawned by Screamers they aren't likely to kill you but damn are they a pain.
Nightmare Fuel: The Worm-Heads the way they move and sound is so unnatural.
So Bad, It's Good: The voice acting and dialog is so horrible but it's so funny especially Maxwell and the Geist's.
That One Boss: Drago-Bat the boss of stage 3 unlike Tri-Serpent comes off as cheap and teeth grindingly annoying and being a glorified Mook Maker makes him look like a coward.
