This is the first real stage from Super Mario Galaxy - the Good Egg Galaxy!
There’s nothing unusual here, so it’s just a standard brawl. Of course, there is that house in the middle. Perhaps it could be used to your advantage?
One key feature in Super Mario Galaxy was the gravity. That is, every planet had its own gravity. However, this will not be applied for this game.
This is just one of the many locations in Galaxy Tours. No matter what changes happen, just go with it and have fun!
