Are you good at memorizing enough to remember every scene in every second?
A no would be okay, because in Playback all you have to memorize are just squares instead of something complicated. Use your memory and tap the screen only, no clashes no booms no fallout, just squares. Sounds simple, isnt it? But youll find it more difficult when playing.
All in all, the free PlayBack would be a great choice for you to test and train your memory, which might be helpful for your magic cube puzzle someday.
Come and try your best to have fun!!
