Excellent game, but the balancing is off
The main turret is waaay underpowered, to the point of being nearly useless. It wasn't accurate enough either, even with upgrades. I got to the second to last mission, only to be defeated by a massive balloon with 90,000 hp that destroyed all my turrets in one salvo. A little warning would have been nice, like *Danger* massive freaking balloon coming. Launch every airstrike and build every building you can or you insta-lose.
