Great concept.....needs some minor improvement!

Pace too fast at beginning levels..Need to slow down the screen shots so a person has time to absorb....Discouraging when you are doing more guessing than showing memorization skills...There needs to be a GRADUAL increase in the speed of the screen shots at each level and each level should have several puzzles before you can advance to next level...MAIN FIX would be to slow down the screen shots and have a gradual increase before advancing to the next level. This would be a 5 if these improvements were made.

As far as having to do multiple tasks to put in what you memorize....that really makes you work harder to overcome distractions!
