Estimated difficulty: 1.5/10.

Estimated 100% time: ~6-10 hours.

Offline/online achievements: 22 offline / 0 online.

Number of playthroughs: 1 + chapter select clean up.

Glitched achievements: None.

Missable Achievements: None via chapter select.

There are 16 story related achievements. 15 will unlock simply by playing through and completing the game, while the final one, Road to Salvation, requires you to finish the game after collecting every single collectible. Thankfully there's chapter select if you miss any, and you can simply skip to the final section after collecting everything. If you need help with any puzzles you can refer to the dedicated section below.

Scattered throughout the game are blue portable toilets. Interact with one to earn the achievement. You can get this almost 30 seconds into playing the game.

You need to sit in a hiding spot for 5 minutes straight and can only unlock it when you're actively being hunted by a ghost. You can earn this as early as the rehearsal section at the start of the game.

This is earned during the dormitory section with DeCyuan Ji where you need to find the crying dolls. Simply stand around until you get killed for taking too long.

You can earn this during HsinChiao's rooftop section. Keep walking into the large strands of hair until you die to them. Be careful the ghost doesn't kill you herself, as that won't count. Alternatively, you can earn this in any section where the hair is. The above is just the earliest.

There are 111 Collection items overall. A good amount are story related, so I suggest playing through the game and searching on your own at first, if you don't want to be spoiled on certain things.
The following list is in the order you'll find them.
