Superb game - escalates in complexity really well, with a great mix of rule content to test the player in different ways. I found balance felt really good, there's a whole lot of tension throughout which was great at tripping me up, but mistakes never felt as though they were punished too harshly with plenty of time to recover if you were able to remain calm and get a few correct calls quickly.
Presentation is great, from the way the music is warped and distorted as time runs low to the sfx which fit perfectly, to the visual style which was clean but still felt authentic to hand-drawn character sheets.
My current high score is 40 completed with 6 errors, but I'll be trying to beat that!
