Nice game. I only had time to play through the first room. Here are a few things I would find nice to add:
1) sound control - game was loud for me
2) more flashlight freedom - in the 1st room, I could not see the upper half of the poster in the dark
3) maybe there can be some kind of manual for the antenna switches and radio frequencies hidden in a drawer or box - I found it tedious to do trial and error

I look forward to trying out the rest
Cheers!
