Game Mechanics or a feature?

[Nemo212]

So in The Battle Cats, there's a series of stages called Cats of the Cosmos, in which you fight various enemies on different celestial bodies. This includes, but is not limited to: Mercury, Mars, the Sun, Pluto, a black hole, Jupiter, Sirius, and Titan (the moon, not Thanos' planet). The final stage of Empire of Cats, the first "storyline", also takes place on Earth's moon. Of course, this would mean that since every cat in the game is potentially deployable on these stages, and a good chunk of the game's enemies show up here as well, they would have a myriad of resistances to all of the lethal conditions of these planets, as well as Type 1 Self-Sustenance. Is fighting on a level/planet in space indicative of a power or ability, or just game mechanics?

I would assume that if fighting on these planets fits into the "canon" of the games, then it would have to be considered. Scrooge McDuck, for example, has this since he could traverse the moon with no negative effects in the DuckTales game.
