Version ID: GX

Fixes & tweaks:
- Added 3 new levels! I'll try to refrain from adding any more because that's not very elegant, but here we are for now. You can find one of them in Rocket Trip as a variant for Horror Story.
- Changed "Force default colours" to "Force high-contrast colours" and made the setting use a slightly altered palette. This'll be adjusted further in the future if needed.
- "Fixed" a bug with Empty (that is, added a solution that doesn't fix it fully but makes it less of an issue)

Adjustments to at least these levels:
- Ghost Friend
- Trapped
- Heavy Cloud
- Torn Apart
- Tangle
- Grand Stream
- Tectonic Movements
