Pandemonium! (video game)/YMMV


 * That One Level: The Lost Caves really feel like someone accidentally put one of the very last stages right at the start of the game. Very long compared to the stages before it, full of Invincible Minor Mooks, and no health pickups whatsoever.
 * Storm Temple, with its indestructible storm balls, the Night Demons that are a nuisance without a powerup, and most of all, a final section infested by a strong wind that forces precisely timed jumps.
