About 11F

"Adam, I'll be waiting on the 11th floor."




Game Introduction

11F
A horror, mystery, and adventure game where the objective is to reach the 11th floor of a building that doesn't have 11 floors.

Story

After his father's funeral, the protagonist receives a real estate rights transfer certificate for a building called "The Origin" sent by an unknown person.
"Adam, do you want to come up to the 11th floor?"
Upon seeing a note with his name, waiting on the 11th floor, the protagonist heads towards that unfamiliar building.

Game Progression

- Feel free to explore the massive building. Progress in any order.

- Fight your way through rooms full of ghosts to reach the 11th floor. There are over 20 rooms with different themes and a variety of ghosts.

- Experience the lives and sufferings of the residents. They may be the clues that lead you to the 11th floor.

- Reach the 11th floor and face the mystery.

Game Progress

The "The Origin" building is filled with eerie rooms bearing traces and stories of past inhabitants on each floor.
Residents, deemed troublesome tenants, have transformed into strange entities wandering the premises. Avoid them and search for the 11th floor that is hidden from sight but still exists. The 'Troublemaker Neighbors' booklet will be helpful.

11F is an indie mystery horror pc game where you explore a mysterious apartment building and try to reach a non-existent rumoured 11th floor. The gameplay involves searching rooms, finding keys, completing mild puzzles, and unlocking your way to the top of the building. The building is filled with eerie rooms and ghostly inhabitants, ready to scare you. The game takes approximately 1.5 hours to complete. + The story is interesing, and is wrapped up quite nicely at the end. + A few musical choices in certain rooms are superbly creepy. + Several of the rooms in the building are quite trippy and are fun to explore. A few of the rooms are highly original in design. - The lighting and brightness in the game are both designed poorly. Rooms are either too bright or too dark. - The game has a very unpolished, low budget, indie feel to it in many ways. - There are spelling mistakes in the game's dialog subtitles. To be honest, when starting the game it seemed like it would be typical low budget schlock like many of these other horror games on Steam, but after playing for awhile I came to see that the game actually shines in certain moments. Overall: 6.5/10.

This is one of many reasons why I support niche indie horror games or indie games in general cause each and everyone of them is a unique experience and this one is definitely something else. I actually enjoyed it and really like the closure the game offered at the end. Overall confusing as hell, weird as hell and eerie, but I loved it and 100%ed it. Great game!

Bizarre but interesting. It's a key hunter, but the fact you can choose what doors to open yourself makes it a little more fun to play. I went into each room not knowing what to expect. The cutscenes are quite weird and combined with a soundscape that doesn't always make sense there's a very surreal atmosphere which I enjoyed. Full price does seem a little expensive considering how quick it is to play through.

11F, developed and published by PUMPKIM, is a psychological horror and exploration game that relies on atmosphere, symbolism, and fragmented storytelling to create a deeply unsettling experience. Rather than guiding the player through a clear narrative path, the game drops you into a mysterious location known as The Origin, a building that should not logically contain an eleventh floor. This central contradiction immediately establishes the game’s tone, inviting curiosity while quietly suggesting that the rules of reality may not apply within its walls. From the beginning, 11F makes it clear that fear here is rooted in uncertainty and interpretation rather than direct threats. The story is presented indirectly and unfolds through exploration. After the death of the protagonist’s father, ownership of The Origin is unexpectedly transferred, accompanied by cryptic references to an individual named Adam and the forbidden 11th floor. This setup provides just enough motivation to push the player forward, but the game deliberately avoids explicit explanations. As you move through the building, each floor reveals rooms that feel disconnected on the surface yet thematically linked by traum…

It felt cheap the settings didn't work and some of things just didn't fit in

One of the weirdest games I've ever played. Some scary moments, but mostly a bit annoying.
