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.
In JSRF, the Tokyo Undergound Sewage Facility. Interestingly, due to the way the soundtrack is structured in-game, the Sewage Facility is the first level where The Scrappy plays.
No "love" for the Skyscraper Distract & Pharaoh Park? Dark color pallete, tons of life-sapping Non-Lethal Bottomless Pits, and very specific series of rails to grind and jumps to make combine into one hellish experience, especially when traveling into the very far reaches.
This troper had a lot of trouble with Bantam Street in the original game to start with, especially with a hard-to-reach tag that always ended up the last one to be done with barely any time on the clock.
What Do You Mean, It's Not for Kids?: Many were probably confused by the Teen rating on the game, even through the first few playthroughs...until they listened closely to the lyrics of most of the songs. One of said songs gives you tips on how to give a good blowjob. Another has you hearing the whispered moans of a loving couple, busy in the sack. You also hear LOTS of references to polyamory. Yeah, seriously. Go listen, it's CRAZY.
