I can imagine this would be quite fun to play with someone, however there was a bug that I noticed, after having picked upon a bonus and then trying to recover my router, and then grabbing another bonus, only the first seemed to apply, and the bonus stayed above my head (was trying to do as much as possible in one small run). Additionally, I think having an option to hold down the button to mine the coins would be nice, I don't mind button mashing, but I think it would detract from mutiple games played as it can get quite tiring after a while.
