A couple of additional fixes and tweaks.
Firstly, as a response from player, Hairy Mary, I have reduced the mouse sensitivity by 50%. Hopefully, this will make for a smoother experience.
Level 01 - The Lost Valley
Flipped the notes around on both monoliths so that the player finds the note relating to collecting fairy rings and rock piles first.
Level 02 - The Swamplands
Fixed a disappearing and re-appearing bush
Level 07 - Snow Caves
Moved the exact respawn point to bring it next to the respawn marker
