Really nice and complete game! The gameplay is fast and fun. I could imagine that adjustments could increase the duration of a run, but it is also fun as a snack sized game. For me, the difficulty ramped up so fast that I had to try multiple times to really get a feel for avoiding the arrows and zombies. So, it was great that I could restart easily. One thing I miss is seeing how many coins I got before I died, as otherwise it's got a very complete set of features and it's a well rounded experience.
