was a perfect game…

…before the recent update it was perfect or near perfect, played it all the time, and LOVED it. The games were a guaranteed amount of time each, between 1.5 to 2.5 minutes each, I knew my time investment, and chose it. Now the only way to play, is open-ended timing, just play until I lose all 3 stars. I can still limit it, just by artificially losing, but it’s not the same with that. I don’t know which way is ultimately better, but I basically don’t play any longer now. This dev makes truly great games, so I hope he finds a way to have a choice in gameplay.

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!

Underrated

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