Letter I received:

Hello I am *** and just so you know a little about me I will tell you my 3 favorite game genres, my 3 favorite are horror, survival, and FPS. The theme I give you is "Endless Snow" Make whatever you want of this but I hope you make it cool.

Ok, lets talk about this. My first thoughts are the following:
I think about some snowblizard kind of landscape. Maybe yetis? Or some other preditor that is hunting the player. Then I remembered some old game that had a cool mechanic where the monster only moved when you looked away. Something like the wheeping angles in dr. Who.

• Here is an official video.
• Here is some additional information

I would like to take the "engine" used for SensenCemetary and modify it, so it supports the following stuff:

• Show a blizard, limited sight
• Outside areas
• Inside areas
• Some kind of weapon you can collect
• Enemies, and detection when they are seen; + a clever system to recognize when an enemy is suddenly in sight to play a scare effect sound
• Some reason why the player needs to turn their back
• Doors that can open and close
• Some indicator that an enemy is on the loose.
