This game starts at aprox 21 minutes in - such a good story, really makes you feel like someone in the situation, as always from this studio wonderful character design and pacing with a story that keeps you guessing right up top the big reveal 

Thank you for playing Umbra Mortis and FuneralIt was delightful, once again, to watch your reading of the story and the characters. Stay well, stay safe!

Great pacing. It was fast paced and flowed like a movie. The atmosphere and world that was created was very fascinating and mysterious.

Hey Guys

I enjoyed playing this game, it had just the right amount of interesting dialogue to read and the right amount of terror!!

Here is my playthrough: https://www.youtube.com/watch?v=t9-kHGWZmg0



Hey iPossum, thank you for playing Umbra Mortis and for posting your play-through here!

For all the doom and gloom it seems when one door closes a window opens for the character. :) A dangerous window but still, nice work.

Hey Cryptic Hybrid,
Thanks for playing and for posting your play-through here. We enjoyed watching it! As you observed, Umbra Mortis may be part of a larger story, one that dwells in more detail into the darkness that befalls the main character.
Have a wonderful day!

Looking forward to more UM. ;) 

Lemme tell you I was so intralled by this game. I couldn't even commentate because I was so sucked in. 10000/10 amazing story writing.

Hey there, ScaredLuna! Thank you for posting your awesome play through of the game and for your kind words! We loved the video.

Thanks for watching! I am wondering why when I tried to quit that Microsoft tried to open an application, are there hidden files for the game?
I really enjoyed the story and I hope that you guys will keep up the amazing work!


Thank you again for your kind words . 

We use a standard game development platform without any additional files, so that quit behavior is odd. Since we develop on Mac (which doesn't have this issue) we haven't noticed this,  but we'll try to replicate this on a Windows machine.  Thanks for the headsup.

Hope your throat is better now :)

It is. I dont think I warmed up enough so that happened lol. Thanks for uploading the game when you did, it was really refreshing to play!
