I've been training for over 2 weeks now and I'm hooked. Should've gotten to it earlier I think, it really does help with my uni studies! I've gotten 20 twice now, 2nd time was when I couldn't speak (first time) - it seems much easier to ace it that way; I think the criteria for speaking games are tough - it's very difficult to read passages that fast! My faves so far are the word memorisation and low to high - both have seem great improvement too
I do hope the 2nd iteration gets localised soon! The problems seem much more difficult and varied and really gets your brain working in more than just the prefrontal cortex (probably not realistically speaking). There's also a piano-based sight-reading activity! Gosh that just proves that music helps build a sound mind eh? Non-games. They really are fun!
Jam it back in, in the dark.
