Interesting concept. The white font on light colored background can be hard to read. I'd recommend a more contrasting background color, or an outline or shadow to the text. Similarly, the symbols could use being a bit more different. Having 3 reds/pinks out of the 6 options they can be a bit too close, especially with the shapes being similar enough at that size. It wasn't too bad, but a bit more differentiation would be good, especially for color blind people.
