Is Don't Notice Me crossplay?

Crossplay does not apply to Don't Notice Me: it has no online multiplayer.

Don't Notice Me is an adventure puzzle game where you play as Mika Kittinger, a normal teen girl who just wants to get back a love letter she gave to her crush. All you need to do is sneak into his room and find the letter before anyone notices. You may need to find his address, break into his house and crack the codes on all the locks he seems to have in his room. You may even get an opportunity to snoop through his phone and computer while you're there.
