Sort of felt like a mix of luigi's mansion (the hoover), mario sunshine (the cleaning) and a walking simulator. there's not much too it, you go around sucking up goop to clear each area, you scan alien plantlife and you occasionally fight lil goop monsters. seeing the reviews for it a lot of people didn't like it much, mostly due to the lack of challenge and that the gameplay doesn't really change much from start to finish, but go in expecting a walking simulator and you may enjoy it more.
