The first game was excellent, with just the right way to keep its solutions cryptic yet solvable. This one...not so much. Particularly on the morse code puzzle, which can have a flawed translation. Add in the fact that it's on a timed quiz (30 seconds to answer two different questions), and it's more frustrating than it needs to be.
One little nitpick I have is whenever the game keeps pausing for a tutorial. Usually, it's really confusing because I'm not looking at the small box on the top of the screen, so it's confusing at first why the game stops for no reason. There's no composition.
