I am still chasing that sweet green checkbox for being fully verified on Steam Deck. Although those in the know can tell you it plays beautifully on there already, there are some sync issues that could make it annoying to switch between deck and PC and downgrade us to only "playable".
While I was tackling that, I went through all the bug reports you lovely, lovely people have sent through the game's feedback menu (thank you! exoflex) and fixed some small issues with particular cards and rare errors. Here's the list:

• Typos typos teh-zypos! ("only" 20 of them)
• Make Small Skills Boost perk and Clear Minded status roll their chances separately instead of adding them together in a confusing way
• Fix Bravely Helping to Fight and other +1 to total cards showing bonus beside the total, but not actually adding it to the total on rounds 2 and 3
• Fix Tracking the Airsquid card text to explain it only affects physical cards
• Confirmation dialog when forgetting or not forgetting a card while relaxing, so it's much harder to skip by that option by accident
• Warn in a popup the first five times any file fails to save during each play session
• Slightly speed up first game boot after install or update (stop unnecessarily recompiling story files)
• Fix controllers not closing text input popups on Steam Deck
• Hide resolution and quality settings on Steam Deck and stop syncing them between deck and pc, just default to what works best on that specific hardware
