Fun game and very simple to understand.
Maybe the pacing is a bit slow at the start when you don't have any upgrades but other than that very fun. Great job :)
Thanks. My last few furious hours was on pacing. In the last thirty minutes it changes from an infinite scroller to being limited to the size of the screen. I was also balancing bonuses and increasing difficulty and urgh... I think I got it ok but it can be improved as you say, Thanks for the spot on feedback :)
