The silence is covering your spaceship step by step! The rooms are filled with a bunch of scary things and ghosts. It’s time for you to build your own spaceship and get rid of all the monsters and creepy things. But you’re not alone. There are a bunch of crazy monsters that want to kill you. So be careful and make sure that you don’t get caught by them. Build the best defense system you can and try to stay alive as long as you can. And remember, you have to survive until the last monster is killed.
