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.
"Found Germany's whip. It's rather worn from use..."
When one of the Greys is in the same room as Canada, it ignores him. Looks like being invisible does come in handy.
Also, one of the options (sadly not used) at this point is to 'pour maple syrup' on the Grey.
Well, the correct option is pretend to be a piano! I think that's just as good.
Under England's Equipment, his accessory is a "Pathetic Scone". The description is "Something that was supposed to be a scone. Very pathetic."
Spain is great at breaking the tension: when he finds the other nations trapped in a cell, he thinks someone put them in a zoo. Later, one of the Greys shows up and he's terrified, while everyone else is pretty much used to it; then a second one appears and he's even more frightened, while the others are mildly surprised.
"You want to know why I came back? Because I can't think of a reason why I wouldn't help my little brother!"
France comforting Canada when the latter thinks he's useless.
Russia and his sisters reuniting at long last. Doesn't help that Russia told them to go home but they chose to stay because they were worried sick for him. And then Belarus throws him a scarf that she and Ukraine found as a reminder that he still has them.
The moment when Italy manages to make the jump from "I want all of you to escape" to "I want to escape with you." Being willing to die for them was exquisitely noble. Deciding that he'd rather be there for/with them proves that he not only loves them, but accepts that they love him too.
Fan Nickname: Jfen has created a couple, including "DetectiveCanan" for Canada and "Tommy" for the monster that is attacking the nations after Germany calls America's alien friend Tony this by mistake, to differentiate between the monster and Tony.
Fridge Horror: The generally accepted theory that each of the red numbers in the room with the key represents one time loop, while the number itself represents the number of survivors who got to that room in the time loop really makes you stop, think, and realize just how many times Italy has gone back to try and save everyone, only to watch his friends die, again and again.
Doubly bad when you take in the amount of '1's and '2's, especially considering you need at least three bodies to get to the room.
Not to mention the times when they didn't reach that room.
Other theories state the numbers represent the number of people who died in that loop. Still has the same fridge horror though
Fridge Logic: Germany says he needs tools, but then what did he use to install that iron door?
Also, how the hell did France, America, and Prussia get in the basement when the door was locked and the key for it still was hidden, along with the cell door key?
Hype Backlash: Due to the popularity of the game in the fandom, it's pretty much unavoidable. Some of the detractors' complaints are that it's not as scary as the original and it's too melodramatic/wangsty.
Iron Woobie: England. Despite getting killed the most and losing your eye sight depending on the time loop, he still manages to keep a strong front especially in front of America.
It Was His Sled: One of the plot points is that Italy keeps rewinding time to get everyone out of the mansion. The only way to avoid knowing about this before it comes up in the plot is to not read the comments or look up any fanart.
Also, most people who start Heta Oni find out what happens to poor England in part 16 LONG before they arrive to that point, thanks amount of fanfics, fanart, and comments about it.
The Tony monster look a like with unsettling music in the background.
Germany's theory on how he tripped: a hand grabbed his ankle. Doesn't help with the random image of a hand on top of the screen.
Okay, for a moment, imagine that you and your closest friends go to explore a supposedly haunted house together. Once you get in, you can get out and a monster starts killing everyone dear to your heart. THEN, you get the ability to travel back and save them; and FAIL everytime but, you don't want your friends to figure out. So, there you are watching your friends die again, and again, and again, over and over for who knows how longAND you are also losing the memories of EVERY bit of time you spent with them, good and bad. The worst part? You think that it's ALL. YOUR. FAULT. How would that feel? It's pretty terrifying stuff, isn't it? Well, now you know what Italy went through. It's a miracle that he hasn't lost it yet...
In the room with the cave leading outside, there is a large hole in the wall. Inspecting it gives you the option of having the character lean inside for a better look. If you do this, the screen goes black and you're informed that you can't see anything. You are then given the option of crawling back out or leaning farther in to try to see something. If you crawl out, nothing happens. If you lean in more, there's a sound like a watermelon splattering, and the game is over. While the screen is completely black.
Scrappy Mechanic: The final version of the playable translation allows Steve to appear randomly after a certain amount of rooms. You can't battle it, and it'll sometimes appear when you enter a room from which it is very difficult to run away.
The program is really glitched too. Steve often appears in the wall.
Ship Tease: They are very minor but the main focus seems to be on Germany/Italy, Spain/Romano, America/England, Russia/China and Japan/China (the last two are more one sided and America/England has been getting more of it recently). There was also a blink-and-you'll-miss-it moment of one-sided France/Italy and some Prussia/Japan.
