Update 1.2.5.0

This update is generally dedicated to small improvements and bug fixing:

• Fixed audio still playing while the tab wasn't focused/when you exited the browser
• Fixed screen transitions (they actually work now!)
• Optimized code to not give me a headache
• Added a "Thanks for Playing" window at the end
• Optimized textures for mobile
• Added a trigger warning at the start of the game

This will likely be the last update for the game (if no other bugs show up.) 

Thanks a lot for the support over these two weeks <3
