I love SCP-Games!
The atmosphere was great! The art-style and graphics were really good too!
I had a few issues with some of the smaller mechanisms to progress, like the tiny lock on the door, which is practically invisible if you turn off the torch which you can not reignite haha. Perhaps a flashlight would serve well in this demo. And then the fact that you have to left-click to use items, like when unlocking the locked door.
What I liked the most was the subtle scares from afar! Great work with that!
Other than that, it was really a fun demo, and I hope to see the full release in the near future!
