Sorry if this is going to sound shameful, but I doubt the human eyes and body can react fast enough to even match or correct the symbols. Some people (Like me) would actually take well over a dozen times just to remember everything. Let me reiterate you have to have an insane reaction time just to react fast enough to catch on xD. Just shows how slow my mind works.
The animation on it is great. The only complaint I have is the reaction time required to match or fix the symbols.
