About
One wrong door, and the Atrium will swallow you whole.
You awaken in an ancient Roman hall that loops forever. The only way out is to identify what doesn’t belong. Statues turning to face you, banners changing colour, footsteps behind you - anything could be the clue. Choose wrong, and you’re cast back to Hall 0. Choose right, and the Atrium lets you progress.
But it's not as easy as just spotting anomalies. Sometimes, the anomaly is obvious - the problem is getting past it.
The halls aren’t empty. Angels of death drift silently between the columns, their presence warping the air. Stranger things lurk beyond - entities you can’t yet name, but will come to fear. Some can be avoided… others demand confrontation.
Spot the anomaly – Each corridor hides something amiss. A banner bleeding new colours. A statue’s eyes that follow you. A torch that burns too cold.
Left or right – Anomaly detected? Take the left door. Nothing wrong? Take the right. But beware: the Atrium has a way of warping your perception.
Puzzles in your path – Sometimes the left door won’t open until you solve a challenge; locate a hidden key, decipher an inscription, or answer a cryptic riddle.
Lurking Terrors – Angels of Death and nightmarish beings haunt the halls, punishing the slightest mistake.
Grow Stronger with Every Run - Your journey is never wasted. Earn diamonds to unlock permanent upgrades. Like Hindsight to review missed anomalies, Foresight to glimpse anomaly odds, or a Radiant Sword to strike down Angels of Death.
Conquer the Final Trial - Hall 10 holds the Atrium’s ultimate guardian. Only the strongest souls will survive what waits there.
Optional Jumpscares - Too scared? Turn them off in settings.

great anomaly game with additional challenges and minigames. worth the price if you continue to explore after the initial playthrough.
这个游戏非常的好玩 没有吃过屎的兄弟们一定要尝一尝
Great game, interesting concepts for the anomalies in each room which makes the experience playing experience enjoyable
I am enjoying this. Its a non scary anomaly game. Its funny and also has some wtf moments. I enjoy it, its hard enough that I havent beaten it yet but its not so hard you cant. Its not a "one item has moved slightly to the left" its more of a "The entire shelf contents have changed" type of game
Very fun and replayable! Retains the (optional) horror elements of classic anomaly games like exit 8 without becoming a walking sim or generic.
