Version 2.2 Update fixes and changes + Linux

Hello everyone!

First of all, thank you to everyone who played the demo, including during the game jam and streamers! I've gathered a lot of very valuable feedback and have made a few adjustments. I've also added an experimental Linux version, though I have yet to be able to do rigorous testing of it yet so there may be issues with it.

Changes and fixes:

* Modified the layout of the caves (swapped Louis's room and the puzzle room) for better pacing. However, you can now fight the boss without talking to him beforehand if you get the blast pods early (might change this later).

* Moved the shortcut switch in the rafflesia room to the upper level and zoomed out the camera in the cutscene.

* Adjusted the layout of the vines in the vertical shaft leading to the upper level of the pit.

* Added two tutorial signs, one in the pit at the start, and another in the skeleton chamber

* Added a bridge, another toothworm, and a new chest to the skeleton chamber

* Replaced the sapphire gemfruit in the breakable wall with a chest containing it.

* Jars and pickups now disappear properly if thrown into pits

* Added more facial expressions and animations to Louis

* Modified the appearance of the elf in the opening cutscene as well as the beehive fragment when the troll falls in the pit.

* Revised the geometry and appearance of root ramps and the rafflesia to be more era-accurate and fix issues with the shadow not displaying properly

* Modified the music in the intro to line up better with actions.

* Looped the caves music properly and adjusted the volume.

* Buttons on the main menu now deactivate when starting a new game

* Added some camera collision exceptions 

* Changed the dirt wall in Louis's room to be a single piece so that it cannot be destroyed incompletely.

* Added the unsheathing sound to the sword when switching from holding a blast pod to the sword

* Fixed a missing climbable location

* Fixed a bug where the boss fight would trigger before you obtained the blast pods

Still to come:

* Adding text progress prompts to the opening text

* Fixing an issue with mouse support for pause menus (arrow keys + enter still work)

* Adding a wander state and blood particles to the mite

* Adding particle dust to the dash

* Optimizing particles

* Adding more collision exceptions to improve the camera

* Fixing the climbing animation glitch

* Adding a propeller to the rock elevator

* Implementing more facial expressions for the bee

* Adding some animations/shots to the intro cutscene to imply the hunters were not outright killed by the troll.
