I downloaded this file earlier before you did, mythofreak! And posts like that will get written down on your AoMH permanent record! Anyway, I will now share my opinions about this file:
I'm giving this a three and a half because while it is simple to create and has some problems, it is also very unique. I love how you used catapults to attack the earth replicating meteor barrages, however there's a problem in which the earth will eventually vanish after a while when its health will reach zero. I also find it bit boring that I can only see one side of the earth over and over again and I suggest adding a camera track that rotates around the earth showing its different sides and maybe add a few armor glow SFX in the black background to replicate twinkling stars. Other than that, this map is unique.
