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.
Bad Export for You: The U.S. version had the entire story stripped out of the game and replaced with a shoddy Excuse Plot in the manual. Note that the game was reverse-ported to the Genesis from the Sega CD.
Big Lipped Alligator Moment: Level 5 has Earnest dumped onto a moving train filled to the brim with banditos, he has to get a golden idol haphazardly placed on one carriage's roof, he battles a monster made of coal and escapes via a biplane stashed on another carriage. He never seems to mention this crazy experience to Annet and Zigfried again.
Even better: This occurs right after Earnest gets knocked unconscious in the previous cutscene. How that leads to him, now conscious, being dumped onto a train from outside in midair is anybody's guess.
So Bad, It's Good: The entire damn game from the QWOP-style movements of Earnest to the ridiculously weird enemies that explode when he kills them.
Uncanny Valley: Earnest, Earnest, EARNEST. His movement, specifically.
