The boss of Stage 7. Kurosuke's built up to be more terrifying than his previous appearances thanks to now having Clione embedded in his body, but one of the traps put in place specifically to combat it can take down most of his health without you having to do much other than pull a lever. While that particular trap does have diminishing returns, the equipment you can reasonably have at this point ensure that you barely have to attack after it ran its course.
The final boss Extend Terashima, while getting close to him can get tricky due to the fact it can attack in multiple directions, the arena in which the battle takes place is so big that you can completely avoid him and even rest up to recover HP without having to worry, since Terashima won't actively go near you. There's also an extend machine that can revive any dead party member as a young adult, meaning that dying isn't an issue.
Ass Pull: The guy Sachika finds at the very end is the last human on earth before she came along. Yet it's never explained how he survived the Luciora attack. This is further elaborated by the fact shortly after the scene you see the Extened Machine's life count go up which could mean anything really.
Breather Level: Stage 5. Once you get used to its gimmick of dropping you at one of several starting locations at random, its bright atmosphere coupled with a lot of room to maneuver and being sandwiched between Stage 4 and 6 makes it a relaxing breeze.
Broken Base: Whether or not the Sony censorship is a good thing.note Basically, they removed the bedtime events where the characters are children and gave Sachika a different dress in order to prevent controversy, arguably creating more.
Creator's Pet: Both Mirai and Sho are often viewed as this. While they help the characters via Conquest Videos, they are not very well liked for being annoying.
Crosses the Line Twice: Attempted with Sho's humour whenever something dark happens. It ultimately doesn't land, however, and is just excessively cruel.
Boars are the first creature that can cause problems due to their charge attack, which does heavy damage and knocks you to the nearest wall. They wouldn't be so troublesome if not for the fact that they tend to spawn in one way corridors, meaning that unless you are fast enough, you are getting hit.
On stage 7, you'll start encountering Shadow Creatures. They'll stand still as long as you are looking at them, but as soon as they are out of your field of vision, they'll move extremely fast, get behind you and start attacking. What's worst is that they start moving as soon as they spawn, even if you are nowhere near them, meaning that more often than not, they'll ambush you before you can notice they are there.
All the sin creatures can potentially qualify, since they can spawn in places that, unlike the arenas where you fight them as bosses, can make it difficult to avoid their most damaging attacks or can potentially be surrounded by other creatures.
Enjoy the Story, Skip the Game: The gameplay received mixed reviews; this is probably the reason why the English version has a lower difficult mode for those who don't care for first-person dungeon-crawling games and just want to enjoy the story.
Genius Bonus: Mirai is a sheep because the first animal to ever be successfully cloned was a sheep named Dolly. Mamoru references the animal himself during his chapter.
Memetic Mutation: People describe this game as Goat Simulator 2019 in comment sections on Youtube.
Moral Event Horizon: Kurosuke crosses this after killing the Sachika 2 times (the second was before she was even a clone). Daichi also crosses this after revealing he caused the end of the world along with Mamoru.
Narm: The silhouette artstyle used for The Extend TV when they show each character's past, which unfortunately ends up making the scenes look a tad silly as a result.
Nausea Fuel: Seeing the bedtime events with the characters as middle aged and old people can be pretty stomach churching.
Overshadowed by Controversy: The censorship issue. Censorship is already a big issue among some gaming fans as it is, and the censorship of Sachika's content is often seen as a pointless move. Though even then, the bedtime events are enough to overtake any discussion about the game themselves, due to the characters mentally being adults in the scenes providing enough grey area.
The Scrappy: Mirai and Sho aren't particularly well liked, mainly for generally being annoying and ruining serious moments with attempted black comedy. Though they can bring out funny lines once in a while, they often fail to actually be funny.
Getting the right prerequisites for certain events can get rather tiresome since they can require character to be in certain stages of life. Need two characters to be adults, but one of them's a child? Just walk around a bit for the day transition to trigger! Whoops, the other character moved on to being middle-aged? Better luck next time!
Breakable walls. Some can be broken down with a craftable weapon, others require Clione powers. It's not made clear which damage types destroy which walls, and using Clione will raise your corruption percentage regardless of whether the attack was effective or not.
Tear Jerker: After the Extend Machine breaks down, the cast begins dying one by one with the third Sachika counting down the number of humans left till extinction, breaking down more and more as her foster parents die.
That One Level: Stage 4, Stage 6, and Final Stage are regarded as the most difficult, in terms of puzzle solving.
Stage 4 requires to pass through doors that would open with certain items on pedestals. If said item was lost or thrown away, you'll have to backtrack to previous locations to find that specific item to move on, only to come across a trap-door puzzle with panels that'll open the floor and drop you to the lower level if done the wrong way. This is especially difficult because if too long is taken, Kurosuke will show up and force you to flee.
In addition to that, one puzzle in particular can actually desync if done the wrong way, forcing you to take fall damage potentially multiple times if you make a mistake, and then you have to set it back up to clear it.
Stage 6 is a humongous maze, with constant barriers blocking paths that require certain silburst to be destroyed, needing key cards to open doors and areas being blocked by material that won't disappear unless a specific action is performed, which is never explained what action it is.
The Final Stage has a multitude of floors that have locked doors and scattered key cards in many areas that each have their own puzzles which are even more difficult to solve than in previous dungeons. Not to mention the sheer amount of traps and pits that could throw you off track if traversed incorrectly, with the final puzzle before the Final Boss being unsolvable if all the clues about it weren't checked out, making you to go around the entire facility just to find them.
How many people felt about Olga's storyline, as it is not touched upon in the main story and only seen if you pick up a book in the Mashiro garden tower in Stage 1.
It's stated that Kurosuke has the potential for taking over Haruto's body. Sadly, this was never explored.
Tough Act to Follow: The game is a victim of this, as it has a hard time trying to live up to its expectations to all the popular Spike Chunsoft games like Danganronpa and Zero Escape in terms of gathering attention of the company and more of the fans itself.
Vanilla Protagonist: The character you first play as, Haruto, is pretty severely lacking in character compared to everyone else. He also doesn't really commit a sin, as he was too naive to see the things that got the woman killed coming and fought against it happening as much as his job allowed.
The Woobie: Every one of the main characters to an extent. Given that they are stuck on an Island with humanity extinct and they are the only ones left. Yuma, Rinko, and Ryo have it ESPECIALLY bad. Zen and Mamoru (the latter is the mastermind mind you) qualify as Jerkass Woobie
