Good game. Although *SPOILER* there are like a dozen endings where future Todd loses the earpiece. He's pretty terrible at avoiding the ONE thing you really shouldn't let happen with a device like that.
The secret to taking down the blimp is that its firing range is just a bit shorter than your planes. Thus, you can take them down without getting hit as long as you never get too close to them.
4/5. Would be 5/5, except for the stupid issues of limited inventory space and losing money on selling items. Allowing irreversible mistakes in a puzzle game is NEVER a good idea. Especially if it's not clear when you're making a mistake.
