Missed Call Demo Of The Demo Update 3

Yet another minor update mostly fixing bugs

• Added a hiding mechanics page

Thanks  beboeverbebo  for the following updates:

• Fixed a bug that crashed the game when exiting the first room without interacting with the light switch
• Selection rectangle was way too invisible at lock ui, so I changed the color and thiccness of it(see pic1)
• Added "Press X to exit" text to some pages
