Demo transfers now work when using Proton, which Steam uses on Linux and Steam Deck.

If you haven't launched the game yet, it will just work.

If you have already launched the game and have data in the full game and want to transfer it from the demo instead, do these steps:

1. Launch Full Game
   
2. Delete save slot you want to transfer to
   
3. Exit Game
   
4. Launch Demo
   
5. Open save slot you want to transfer from
   
6. Toggle an item on or off in the cat shop
   
7. Exit the shop. You'll see a save icon in the bottom-right.
   
8. Exit Demo
   
9. Launch Full Game
   
10. Select the save slot. It will show New Game, but when selected, it should do the save transfer.
