The game puts the "masking" definition right in the start page, no need to deduce. I also dislike how any form of self care reduces your masking even if you're alone.

It's designed to make you lose in a couple of days, which would imply you're not a highly functional autist, and hence I wonder how the heck did you get a job without others noticing your autism?

Like I said, implication is a bit weird.

For example, self care with video games would be different. I think the author was just trying to demonstrate that self care in the normal sense isn't the same to spectrum folks
