The reviews are very mixed, I think it’s because a lot of people will not be able to max out the ranks. And a game you can't complete is downright annoying. If any of you are like me, no matter how many times I try i can't get much more then rank 13 on each mode.
At least with brain training stuff you can improve but this is eye-hand coordination speed, with is largely genetic. Its why some people find it easy to learn to play a guitar and others struggle.
Unlucky for me, i don't have the ability but it okay I'm good at other stuff
