Stuttering
Only one crash at a specific spot after 10 hours of play
Some areas of the game aren't optimized well and had stuttering. After over 10 hours of play, I only experienced one CTD (the first time I started princess arcade minigame). It was definitely playable, but with these performance issues already occurring on Windows, you will likely (at best) experience the same issues.
No additional launch options used.
Worked 99% OOTB with Proton stable, except the Spike Chunsoft logo video didn't play. On Proton GE it does, but I didn't notice any other issues with non-GE. Cloud saves sync successfully to Steam Deck, but so did my graphics settings, so you may have to adjust those when switching between devices.
