2/5
Reasons:
1. No reason for buying the other Choppers, the Thunder is the best by far.
2. The Chinook automatically flys up until it hits the ceiling, without using fuel. You can use left and right keys to basically have an infinite fuel source.
3. The Big Mama doesn't fly up very good, took a bit of work to get it off the ground for me.
Oh, and you should make it so the cash doesn't go below Zero, that way people who fail while trying to get used to the controls won't have a huge debt.
Found a Glitch..>.>...When a frost tower upgrades past the Big Gold Star, its damage starts to go down :/. At level 19, it was doing just over 1k damage...which isn't fun for the final boss.
