Fun game! Would be cool if asteroids gave a hit indication when they take damage but aren't destroyed yet. Could also use some music. Those sentry turrets are really strong! Nice job!

I love the alternating firing angles! It threw me for a bit of a loop initially :)

Overall, great game with some more depth than a traditional arcade shooter with debating over an automated sentry or another cannon.

Using the moon as a launchpad for saving the earth is a cool idea. Like the way the two launchpads work in tandem. Good game !
