For a flash game, this is perfect. The difficult was just right, there is even a plot, the cutscenes are great, the animation and music are awesome. Also the length is set just right to me. There are a lot of elements to work with, and each world felt different.
I felt compelled to try to earn a gold medal in all the rooms, and the feeling of achieving it was great, specially because I did not thought it was a waste of time.
A small thing that did not quite live up to the rest was the sound effects, because for some things they seem missing.
Well done Jinxology!
