Can you please add a colorblind option, when there is purple and blue (I am assuming, or maybe its pinkish purple or lavender), its really hard to tell which is which.
the badge probably requires that you dont click anywhere where there isnt a difference, there was a badges with such a requirement in the other 'difference' game
seriously, freaking lame, there should be a timer while its balancing, it seriously just chilled for 230 of the bonus seconds before it decided it was a perfect balance
