In the Trace-Walking challenges, Mario must
walk along a path, which he can no longer see after a few moments; if he gets a high enough score, he wins a Power Moon. For the Moon Rock bonus moon, he must simply earn a higher score on the same challenge.
In the Picture Match challenges, Mario must
take the parts of a Goomba’s or his own face and place them on a blank face. If he scores high enough, he gets a Power Moon. Thanks to Moon Rocks, he can earn a second moon in these challenges by doing this again with nothing but the face’s outline helping him.
My question is: how are these graded? Toad in the Picture Match puzzles claims that it’s graded on accuracy, but that doesn’t explain how much is deducted for what type of errors.
I’m grouping these two challenges together because I’m assuming that, while each is slightly different, the scoring will be along the same lines for each, since both involve matching something to a disappearing background. But correct me if I’m wrong.
