Release 1.1.0

This is the first set of post-submission updates:

• Replaced stage failure sound - finally found a good sad cat sound (no more stupid out-of-theme spooky sounds).
• Reduced the victory sound volume of the stage "Facing Fears" to what it was supposed to be 🙉
• Added a start screen (with Start Game and Exit Game options). You can now exit the game without having to press Alt-F4, yay! I'm still figuring out UI Toolkit so this will become a normal in-game menu at some point 🤞
• Replaced the default font with something more feline'y 🐈
• Removed the in game UI buttons (Restart and Toggle Fullscreen), the bottom label, and tweaked the scene name visuals.
• Finishing the GG stage now takes you back to the start screen in order to remove some confusion that the scene introduced.
• Gave the cat telekenisis (clicking on any glass will destroy it). You can pretty much bypass any stage with this by just clicking on the glasses. This was used during development and will be removed in a final update.
• Pressing Esc will take you back to the start screen (to be replaced with bringing up an ingame menu).
