I had fun, because these card games are just silly addictive... but I never understood the 'energy' part of the concept, i couldn't figure out WHEN I could move. Other than that, I never really felt out of control, but I WAS having fun.
I guess I should've made it more clear that each vertical level has a specific number that forces you to move when you have blue (energy). The number is located on the rightmost part of the gray screen.
