New options have been added

Music Mode - added the option to switch between dynamic layered music that changes in response to game events(the previous default behavior), or opt for prerendered static tracks.
The 7 music tracks in the game can now be individually disabled or favorited. Disabled tracks will not play, favorited ones will play twice as frequently.
Hint Mode - added an option for choosing between suggesting any applicable hints immediately, after a delay(this was the previous default behavior), or never showing hints.
Fold Engine - added a quality setting to toggle between calculating folds on the CPU or the GPU. Both of these options should be functionally identical, but will have different performance implications on different machines. CPU mode is recommended if you don't have a dedicated graphics card, otherwise GPU mode (the default) should result in better performance.
Quality Presets - Presets have been added for various quality and screen settings... There are general quality level presets for Ultra/Balanced/Low/Potato, a preset recommended for systems with an integrated GPU and three Steam Deck presets for favoring quality, performance, or battery life.

Minor tweaks and enhancements

The zoom level on the level select screen is now restored when transitioning from having a level category selected to the full zoomed out view.
Performance on the first frame of swapping between levels has been improved, especially so on lower-spec GPUs. This change makes cycling through levels much smoother.

Fixes

Fixed a case where the top layer folding UI overlay could get de-synced with the actual top layer folding status.
