Post-Jam Bugfix update

This patch includes mainly bug fixes. There is no new content.

BUG FIXES
Fixed the ending screen always assuming that player came from Speedrun Mode
^This also fixes the ending dialogue not playing properly.
Fixed the Diamond Dormouse skin being unlocked by default, Beat the game in Speedrun Mode in less than 8 minutes to unlock it.

VISUAL
Fixed the Diamond Dormouse and Jade Jerboa skins using the same sprite in the Skin selection menu.
Made it more obvious that the blue projectiles are meant to be hit to the boss.
Made the gravity changing areas more visible
Moved the background tiles around in stage 3 for better visibility
Fixed the Icon of the exe on the windows version

AUDIO
Increased the overall volume of all BGM. Remember to readjust the music volume through the settings in the main menu or through the pause menu.
Adjusted the volumes of all BGMs to be more in line
Added hurt sfx to the boss
Lowered the volume of the bounce SFX

QOL
Enlarged hitbox of the blue projectiles so that they are easier to hit.
Added a transition of sorts from the boss stage to the end screen instead of switching abruptly
Added more hazards to stage 3 so that failing a section sends the player to the last checkpoint instead of even further back in the level
Moved some hazards around in stage 2 to require less precise movement

OTHER
Emphasized WASD over Arrow keys in the dialogue
^Likewise in the "How to Play" section in the Pause Menu
Changed the names of the Vshojo member related skins so that it's more obvious who they are referencing
Removed references to Bubi from the credits since nothing related to him ended up making it to the final version :(
