It's fun getting tossed around by bombs :D
Like others mentioned, I dodged them at first thinking they will hurt me.
Also, I would increase the spawn rate of coins (even if it would mean the possibility of having multiple coins on screen), since sometimes I would have several seconds of not having anything to do. I would also increase the time they remain on screen since I could almost never get to them on time - even if I was right underneath, the bomb would launch me too high and by the time I fell, the coin would be gone.
But, very fun, picking up coins is always satisfying in my book :D
