Vibes are fantastic and gameplay is solid. I was able to beat the game by just defending a single satellite (it's difficult to defend all of them given how quickly AI drones spawn over a wide area). Love the music. Flying through the tutorial to get to the play area is awesome.
Sound effects broke for me on my second and third playthroughs. If I had to guess, some signals didn't get reconnected when a new instance of the level was loaded in.
Great work--3D no less!
