If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
Fortify your base with several turrets and start blasting the hell out off the enemy aerial units. Choose your weaponry wisely as each has its own advantages and disadvantages.
They’ll try to overrun your defenses, so you better have an accurate aim and blast them from the sky.
