Any sale recommendations for co-op games or remote play together games that are on sale?

I used to use an app called airmore on my phone and desktop to play music. It does photos and videos too. If I remember you download the airmore app on your phone(I think you have to install it by apk) and then it’ll direct you to a web Adress on your pc. Once there you scan a QR code to pair thr devices and you can cast stuff from your phone to your pc. I haven’t used it in a while but it always worked pretty decent for me.
