Great game, a bit maddening

Like all Sean O’Connor games, this is an excellent game, collects NO PERSONAL DATA of any kind (huge endorsement in my book), and has a couple aspects that will infuriate you.

The Samurai popping his head up can occasionally hide the correct answer, which makes a big difference at the higher levels, when you have like 3 seconds to respond. Certain challenges, like pulling apart the monkeys, also just wrap your thumbs up with near constant movement, making it very hard to do the other two challenges.

Overall, great game and an excellent tool for building selective attention, focus and reflexes!

This game is what, like ten years old? And it still receives updates!

Great little time waster

I have this game on my android phone and my iPad, screen size does make a difference in my score, but gameplay is still great.

The premise is simple, just answer simple questions simultaneously with others or tasks. Reminds me of playing Brain Age from the Nintendo days a little.

Graphics are pleasing, sound is fun, a great little game. Thanks Sean for another impediment to my productivity!
