if this is an idle game, then why does a loot picker punish you? idle games are meant to just run in the background, not to be continually checked upon, and why does Tank mode increase your Health more than your Defense, in two levels only my health has gone up WITH Tank Mode activated, without Tank mode activated my defense has gone up. I'll test this more.
for easy cash (if you have the golden cart with the hang glider), go up and try to hit the shuttle while doing handstand (down - down - up-hold), if you hit it you should get x2 while getting points, then when your in the blue region you use the hang-glider by pressing up-down-up-hold, this will increase your points further allowing you to get 30k+ cash per jump, you can include other stuff like the pole-vault and spam-wacking the trees and bushes for money when you get to the ground.
