The game is fun, although very grindy at the outset. I'm now into my second cycle of episodes and find I'm making more progress with only half hour long absences although I try to only log on when there are alley barrels or my multiplier is due to expire. Which brings me to my lower review score: the Ad Multiplier button. It's horribly unresponsive, when it does work it sometimes will let you click "play" but wont run an ad or won't show "play" but only "ok". Please fix this bug.
