Really good atmosphere, although it was very hard to see some of the objects given how dark it was. The only negative I have is that the objects weren't labeled. Some were obvious but a few others weren't. Overall, a good, somewhat short game that was really enjoyable.
The atmosphere was great with two ghost characters and occasional creepy sound effects.
I was able to solve all puzzles and found most items after zooming in the screen to 150%. The rod above the sofa was so hard to spot, thanks to a comment on another forum.
If you're stuck with a strange cylindrical stone shape, think about heat. :P
Just found the items very hard to spot, but nice game, liked the atmosphere.
