Unplayable if you struggle with green/blue colour-blindness. [FIXED!]
Yeah, I know what you're thinking, who cares about a few colourbliund gamers? But it's not a 'few': there are hundrds of thousands of colourblind gamers. It would have been easy for the devs to add a colourblind mode (such as the one used in Peggle). Why not add symbols on the bubbles or give is the option to tweak the colour settings? The blue and green bubbles in Cranky Cat are indistinguishable to me and no doubt many other people. Disappointing.
EDIT: The day after I created this post the devs added several features, one of which is an option to add symbols to the bubbles. I am one satisfied customer. :)
