Others Mysterious Abandoned Building [Demo v1.27] [Zell23]

[mod876]

i've seen this pixel art before but the "other games" section doesn't show the game I had in mind, are they the same artist?

Most likely its Zell23 they are doing a remake of their Forest of the blue skin/s game!

 

[love2]

I want to play this game when it actually has a story T w T

 

[DoubleCheekedUp]

is there any gallery for us gooners?

 

[twistmas]

I am amused that the game description says that "the focus is on slow exploration, environmental tension, and navigating the building’s floors" meanwhile the header gif previewing the game is of the player being absolutely fucking bombarded by tiddybeasts on all sides lmao

looks cool tho

The game is gallery

Tatsuo went into a creepy building,
Tatsuo encounters monstergirls,
assuming Tatsuo had 14 apples and 23 grapes,
how empty will his balls be by morning?

NO! I refused to kneel and accept your Common Core math nonsense! Give me proper traditional math or give me nothing!

You're US aren't you? Alright then traditional 'math' for you:

Okay so Dwayne has a semi automatic rifle with 5 Mags of 30 bullets each,
assuming his school has 120 students including himself;
and assuming he has fired 2.5 Mags with 100% accuracy by the time Police plug him,
how many students are left alive in the High School?

So, is this still "enter doors one by one and find monster girl" or does it have actual exploration? I liked the pixel art in an early build I played a while back but it was a glorified gallery.

Honestly, there's enough games out there with girls with cosplay cat ears and tails pretending to be "monsters." The genre is full enough of those that Zell can do some nightmarish niche designs for us tetrophiliacs.

Overview:
The game takes place inside a decaying, multi-floor abandoned building filled with dark corridors, strange rooms, and hostile creatures. The focus is on slow exploration, environmental tension, and navigating the building’s floors while encountering enemies and scripted events. Each update typically introduces new rooms, enemy animations, or mechanics, and reflects the author's iterative development style. Unlike his more combat-focused projects, Nazo no Haibiru leans into a claustrophobic horror tone, highlighting tight spaces, surprise encounters, and survival-style progression. Players must explore carefully, pay attention to environmental clues, and avoid or endure encounters with the building’s residents.​

Once you get captured how do you... get out? I just get a black screen and sex noises and have to close the game.

Press the Space bar a few times, it'll reload you back to the starting position.
