I actually wanted to make a breakout bitcoin game a year or so ago, never got around to it. You beat me to it!
The game seems to work pretty nicely, a few hit-test issues but it isn't exactly going to cost you millions in the long run.
It seems to be too difficult for most visitors.
Looks like most just want to get their satoshi with as as less hassle as possible.
I guess the concept is a bit of a failure
Nah man, it's a fun little game to play. I suppose that people do just want fast Bitcoins, but it's an enjoyable little thing.
