Hi! I really enjoyed the demo. I tried the previous one and was disappointed, but this one really makes me look forward to the full game. And, as a chemistry geek, I'm quite happy to find a game with chemistry puns :p
Just to let you know, there was a mistake in one of the quizz questions: the correct answer for the stochiometry of the C8H18 equation should be 2, 16, 16, 18 and not 2, 25, 16, 18 (so there are as much O on the 2 sides).
Except from that, I really had fun with the demo :)
