First off, OK, cool, didn't understand how the double cherries worked, let alone where they were from. Thus, they didn't come up with the concept, by the way, old pinball machines did.
Space is a vacuum, but it's hardly empty until you find something, it's just not filled with much stuff that we notice. Not everything is easy to see y'know...
Invicibiblity is OP, yes, and it should be used sparingly, and a good video game does this. Do Zelda games do this? Yup. Super Mario? Up. Etc Etc.
Game Freak releases under Nintendo, yes. They aren't Nintendo, though. Even if Nintendo is a parent company to Game Freak(is it, by the way?), it's not the same company.
My point is that if it makes sense in the story, it doesn't matter if makes zero sense in real life. An internally consistent story that is disjointed and hard to follow is objectively better then a story that is not internally consistent but is easy to read and understand. If it can be internally consistent and be easy to follow and understand, it's a great story, if it's able to catch your attention and interest you.
