Oh man I love these space hedgehogs! And the rabbit on the speeder xD. I noticed I placed three hedgehogs on top of each other in the tutorial but everything was fine... The completed hedgehog zones blocking the rabbit was a really nice touch, felt like blocking the AI in Civ with the threat of declaring war haha.
Not much to say that hasn't been said, it's really stable and polished, and I love all the little art touches you did :)
