Hello,
I've updated the game to version 1.0.2 using the latest Ren'Py version, which should run better on modern hardware including Steam Deck.
I've also kept the old build in the "old_build" branch and removed the beta branch.
The old build is the original 32-bit build that some users might still want to use in certain cases (old hardware, compatibility, etc).
The 64-bit was tested already time ago but let me know if you find any issues.
Thanks!
