It was great fun as a timewaster, but there was no real difficulty to it. Finished with 10 lives left (never lost any), and around 57,000 points. Super Mega Ultra Combos were fun :D How about also having icons for bonus dice past 4 dots? The bonus value does keep going, but the amount of dots on the square does not.
Also a bit of an anticlimactic end. Ah well.
