v0.3 - Improved movement & audio

In lieu of the feedback recently received for the project, we've made a couple changes:

• There is now a small period of time when walking off of a platform where you can still do a normal jump, followed by a double jump.
• The rate at which the player slows down and changes direction has been increased
• There is now a natural Mouse+Keyboard control scheme.

In addition to those QoL changes, we've made quite a few improvements in regards to the audio in the game:

• Added SFX for throwing the lantern
• Added SFX for picking up petrified spirits
• Added new background ambience
• Updated SFX for the lantern breaking
• Updated SFX for the lantern hitting walls
• Updated SFX for jumps
• Updated SFX for buttons
• Updated SFX for fire
• Some audio will now pan/spatially blend based on where they are relative to the player
• Reworked the balance and mixing for most of the sound effects and music

Additionally:

• Fixed a bug where the lantern will tend to remain on the left side of the player
• Fixed some issues where the lantern would stutter when following the player
