Honestly, a very fun and polished game. After a few tries I got 107. I think it would work well on mobile, with some unlockable skins for your fox and the enviroment. Maybe with tilt controls?
My only issue was that for me it would me more intuitive if the tree rotated the other way than currently when moving mouse. Also an option for arrow keys controls would be nice (my cursor was all over my second screen when playing :P)
Great job!
