Any simple cheats to make it just that little bit more fun?

[Autocrat Daddy Jones]

I've completed the game with 3 stars on all levels and I'm not interested in achievements. What I am interested in, however, is building my complete dream defence on "Home on Derange". Unfortunately, I'm simply not able to get to a high enough level and make enough in level money to even get close. I'm fairly consistently getting well over 100 levels, but it starts to get a bit more dull after about 95 because it just takes so long to earn enough money to buy/upgrade towers!

If there was a simple way to increase the amount of coins you get or, failing that, infinite air strikes then I could keep going until I'd built what I want. I'd prefer the former since it also helps to avoid the more boring slow earning rounds.

If there's a way to do this and avoid be put on the leaderboards I'd be happy with that as well. As I say - I'm not looking to get achievements or spoil anyone's game, just have a little more fun than I'm able to right now...
