I don't wanna be a smart ass, but: your earth is mirrored :D I think you did a great job in turning the old school missile command into a 3D game. The combination of photorealistic earth and minimalisticaly coloured effects is a bit weird, but for a short game jam ok. Bring that in line, add a bit more substance and maybe upgrades or the like and it will be a great opportunity to sink more time into playing it.
PS: Of course I would like your rating on my game as well ;) https://itch.io/jam/gmtk-2019/rate/460633
