Backlog - Log Student Input

[petergault]

In my play testing I've found that kids really love this game. However, they are crushed when they try a word that should work and see that it doesn't work. One solution here is that we should capture each student input for each word. We can then show a list of the number of times each wrong word was selected, and we can add the most common words into the game. There are a couple of ways we could log this data - either through firebase, or by passing it into keen.io, our analytics service. This is a conversation we should have with Will + Marcello.
