Post Jam Update

I made a post game jam version of "The Keys Spawn!" with some fixes and small additions.

Additions:

• Almost all keyboard keys can be spawned now.
  
• The eyes of the player look at the mouse now.
• The head rolls now when the player dies and the eyes are changed for crosses.
• The key spawn check area is a bit smaller now to facilitate spawning in crammed spaces.

Changes:

• Reworked the "Meteor Alert" level. Made it less luck based and more fair and puzzly instead.
  
• Reworked tutorial level slightly.
• Fixed text in background not displaying correctly at different than HD resolutions.
