This was really unique, I like how you could see the ghosts through the planet even though that kinda doesn't make sense but from a gameplay perspective it works especially since the ghosts seem like they can go through the planet slightly? I agree with the others that it felt cramped, maybe needs a health system.. Honestly, pull a few more ideas from other survivors games and you have something really great here. I hope you continue working on it, this game has a really neat twist. Also the story of "teaching the ghosts peace by shooting them" is great
