This is likely my favorite Exit 8 style game i have seen or played, it was a lot of fun, a bit silly, and i loved the Final Hall challenge, it was a lot of fun for how short of a time it took me to finish it but i am excited to play through again and again to find all the anomalies

Highly recommended. Atrium Mortis is a really creative game that encourages you to think outside of the box. I found the platforming to be a bit challenging, but that might be a skill issue. Some people (not me) may find some elements scary. overall, I had a lot of fun the music also compliments the gameplay very nicely. I will definitely recommend giving this a go.
