Good, but needs more.
Once I got going, I started getting lots of distance and cash, and fairly quickly got all the achievements. The only one I can't get is the 6x Perfects. It's damn hard to time those correctly, and I'm not even quite sure -where- the dwarf needs to be hit for another perfect.
My last toss was 117,562 in distance, 5,310 in height, x1.6 bonus, and a total of 18,012 cash. This leaves me on day 37, with all the upgrades, and 21,781 total cash.
Nothing left that makes me want to keep playing though. No highscores to see the ten top people who somehow managed to get a distance of like eight billion, and no further upgrades or achievements for me to try getting.
Overall though, it was an enjoyable pastime. ^^
