Could easily be improved

This game has a big flaw. It only took me two tries to memorize the order of the color/word responses in level 3, which defeats the challenge. (i.e. After two tries, you don't need to read the words, you just focus on the colors and file them in memorized spatial slots.) This could be easily fixed by randomizing the order of the words in the bottom row each time the game is played.

Fun and simple

This is a fun little app, easy to use and fun to practice. My seven and nine year olds liked it as well.

AMAZING FUN.

It was so amazing, I HAD to write a review. It's so much fun, so simple, and so easy and JUST. SO. MUCH. FUN.

Like, it has to be on your iPad. Like, right now. Now if you'll excuse me, I'm going to go finish playing.
