Really interesting concept. I liked the puzzles, althought there seem to be a couple of bugs here and there. On the 3er test I couldn't get the tv to turn on and I was locked in the room, so I had to start over again :(
I gotta say I was not a fan of the font used for top of the screen text, I felt like it put my eyes on too much of a strain.
I also had a bit of trouble getting to display the messages of the letters scattered around or maybe not all of them have a message to display? I couldn't tell.
I liked the concept of the experiments very much so and the puzzles are entertaining. Great stuff!
