Small Bug Fix Patch

Just a little update with some more juice, and some additional fixes for some odd track behaviour edge cases!

Minor Features

- Track unlocks now work if you unlock multiple tiles (via cheating)
- Removed debug keys from build
- Improved the performance of some environmental elements
- Improved the font styling to prevent sub-pixel aliasing
- Added more VFX/SFX to selecting and hovering tracks in the side menu
- Tweaked the SFX for the level select to make it less harsh

Bug Fixes

- Fixed the level instructions not populating correctly
- Fixed some edge cases on logic with halt for fully stacked tracks and halts directly under spawners
- Fixed sounds not tracking to the camera in level select
