Interesting game. It reminded me a little of the old on rail shooters since you could not control your movement. After some balance it could be even better. But it was very fun anyway.

I like the concept of a moon tower defense game where you orbit the moon!

I just never managed to get enough gold to buy an ultimate demolition.
I don't know if there's another way to get gold than to click the cubes? If I buy health or strength upgrades, my health drops to zero almost as fast as if I buy nothing. And when I buy nothing I still don't get 50 gold before the spiders kill me :(
