Thank you very much, I really appreciate your feedback and I'm glad you enjoy the game :)
Regarding to game mechanism, unfortunatelly that's all I had time, I was wanted to make Vampires, ghosts, skeletons and all sorts off enemies, weapons, recoil, collectibles, upgrades even base building and etc etc... but no time...
Regarding to the enemies yes intentionally left them fly through everything due they are ghosts
I'm really Happy you like the game, maybe in the future as soon as I will have some time I will make it better but now I'm working on a survival apocalypse FPS and Tower Defense game for steam and also a smaller multiplayer Fun Shooter for Steam and Google Play store..
