Steam Deck and Linux
The Full Release FAQ says Steam Deck can play Ratatan and is not an officially supported device. There is no native Linux build. Proton is outside the supported list. The Steam page I checked did not show a Deck Verified or Playable badge. I am not inventing a frame-rate for Deck.
If the beat feels late, the in-game rhythm calibration is the setting the FAQ names, not a hidden config file. That control is also covered on PC settings.

Questions
How big is the PC install?
Steam lists 10 GB for both minimum and recommended.
Is Steam Deck Verified?
Not on the store page I checked. The FAQ allows play and withholds official support.
