A tip for the colorblind — check your computer's assistive tools. Win7, for example, comes with a Magnifier tool (Start > All Programs > Accessories > Ease of Access > Magnifier). Using it helped some, and it has an option to invert colors, which helped even more. It looked fugly as hell, but allowed me to complete the puzzles I hadn't been able to previously.
This game is *incredibly* difficult to play for the colorblind. In level 1-8, I couldn't distinguish between *any* of the three colors. Any chance of getting a pattern/colorblind mode? I love this kind of puzzle.
For those complaining about the difficulty levels — they don't affect the actual dice, only the choices made by the AI. "Reckless" often rolls when it should bank, "Cautious" often banks when it should roll, and "Realist" rolls or banks as appropriate. The dice are equally fair for all difficulty levels.
