Roomie is the player character in Out of Space. There are multiple species of Roomies, such as Sharks and Foxes, though their appearance does not affect gameplay.
Every Roomie has three attributes: Stamina, Hunger and Dirt. Each of these attributes incur heavy penalties if left unchecked; as such, they must be carefully monitored to avoid potentially game-ending consequences.
|Stamina||Passively increases, and Usage: Mop, Quarantine Spray, Exercise Bike (11%/tick)||Passing Out, or Usage: Chair, Couch, Bed||Passing Out: Roomie sleeps and slowly recovers Stamina, only waking up when splashed with a water Bucket, or when Stamina is fully restored||N/A|
|Hunger||Passively increases, and Usage: Exercise Bike (2%/tick)||Eating Food||Starvation: Roomie falls to the floor and only recovers when fed||May trigger Game Over|
|Dirt||Certain variants of Aliens, recycling a Cocoon and touching Goo||Usage: Bucket, Shower||Cocoon: Roomie becomes an alien Cocoon and only recovers with a Shower or Recycler||May trigger Game Over|
Out of Space offers a variety of species to choose from. They are merely cosmetic, and some can be unlocked by completing Achievements.
There is a secret roomie only accessible under specific conditions called 'Bucket Head'. This roomie's head resemble's an alien with a bucket on top of it. It is aquired by having a roomie be cocooned and then thrown into space, after they respawn at the entrance and the cocoon is removed they will be wearing this skin automatically and it will become selectable for future games.
