This is a fantastic and difficult room escape style game from Self Defiant. I am not very smart so it took me 45 minutes to get through it with no cheating or hints. The puzzles aren't impossible if you're familiar with the genre, but there are definitely some tricky ones. If you have experience playing this style of game, though, you will have an idea of what to look for and what to write down when completing the puzzles. The only thing I would change is I would make how to go back to previous levels a little more obvious. I could see how someone might get confused. Great game and keep up the good games, I enjoy them a lot and I thought this one was a great challenge.
