Hmm.
Well, seen this several times. Still a little bit addicting at first.
It does get annoying having impossible things though. Example:
50/50 shot left or right, its just a guess, no fun/skill there. Also, did you notice on the remembering thing, the second one, it says "Red, red, red, light blue, blue" however, you have to actually do "Red, red, light blue, blue" to get through.
