Very nice game, gradually increasing in difficulty over time as you get more used to the game, could do with less advertising, but overall it is a good game with lots of variations. I'd love to see a sequel.
What I would like to see: The running training more like a platformer, maybe something like floodrunner, The swimming in birds eye view, having to maneuver to avoid icebergs or land, The Flying similar to the swimming, but avoiding birds and clouds decrease speed, The Climbing is perfect already, + if you like one of these suggestions
There is one thing that confused me, however, I lost my save from ages ago when I received a normal medal on the road track, I earned it about a year ago and then I lost it, I got it back now, I think it was the update which cancelled out my previous achievements, I also had to climb the ranks again.
Brilliant sequel, love the career mode idea though there could be a storyline in number 5, explaining why monkeys hate balloons so much, you included what most tower defense games needed, a FAST FORWARD BUTTON!
