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.

Atrium Mortis initially felt like a spot the difference game. But after a few cycles (and embarrassingly obvious misses) there's quite a good variety to the anomalies that you can encounter. There's some that might get you to platform or find a key to progress, amongst others. There's a slight rogue-like element in that there's diamonds that can be spent in the shop for permanent upgrades. Definitely the best part is the trials once you reach the 10th chamber. Instead of the classic atrium, you're presented with a new room that you will have to quickly learn. There's also the epilogue mode that adds another cool layer on top of the original game so definitely give that a go as well. All in all, I would definitely recommend Atrium Mortis, it's a game that you can get into with no preamble and just get going. The variety in anomalies that you can encounter is enough to keep you playing for a good while. Definitely give it a try!
Spent hours and hours in Moral Dilemma difference finder. More than 20 hours in Atrium Mortis demo and finally got a full game, puzzle which take all my attention and memory skills 100% deserve 10/10. New mode after finishing first part absolute masterpiece. Developer is freak as me in a good meaning.
The halls of Atrium Mortis. They are mysterious, scary (thanks god it exists smth to put this off), but also very funny You need a good eye for sure, as you need to pay attention to the tiniest detail. But its very fun and don't hurt to try it out 🙂↕️
The visuals look good and give the place a nice atmosphere. I also liked how some rooms have unexpected twists which keep things interesting as you’re looking for anomalies. Interesting game overall.

i honestly really like the details and silly rooms.
Excellent follow up project to the dev's first game, Moral Dilemma. Variety of anomalies and challenges keep players on their feet. Even after completing the main Atrium and Final Hall, feels like I have barely scratched the surface of what the Atrium offers.
Certainly more fun than it looks. I wasn't expecting to enjoy it as much as I did. If you like "Where's Wally?" then you'll like this.
Nice anomaly game with a LOT of anomalies and a TON of achievements to hunt for!
Cool take on the platform 8/ observation duty style of anomaly finding game, has decently good replayability as well with all the upgrades and stat tracking available
