Keyboard and mouse input for the phone is a gamechanger for me. Having a manipulatable window that I can drag and drop files to is super nice as well.

Also since Slay the Spire doesn’t have cross-saving and all my progress is on my phone I can play it without staring at my phone.

I agree with you in spirit but would also like to shill for scrcpy in general if you aren’t already using it. Mirroring phone screen to my laptop is fucking amazing.
