If you want to **** your sister with the least amount of issue, protontricks can help you with that, download the patch and use protontricks, then pick the game, the installer will help you pick the installation path of the game and let you install it.
Run fine without Background Recording
You might enable Background Recording for other games, but for this game you should disable the Background Recording, at best it will record without sound(which defeat the point of recording a rhythm game), at worst it will crash the game.
If all you want to play is base game with Afterbirth and Afterbirth+, the game can be run without using any Proton configuration;
But if you want to play Repentance and Repentance+, you'll first have to enable the "Enable Steam Play for all other titles" for the DLC to even show up on the DLC list, then you have to enable the "Force the use of a specific Steam Play compatibility tool" and set it to "Proton Experimental" to even launch Repentance and Repentance+ otherwise it will launch without Repentance and Repentance+.
If you can configure all of it then, the game can run pretty smoothly without any issue from my experience.
