Finised Tutorial level

So... Today I slightly changed game menu and finished tutorial level. I'm sure that it's still not polished yet and there are can be some bugs but... I'm tired for now.

Changes:

• Added some cosmetics in game menu
• Added background music and volume slider for it
• Added tiles in project
• Changed camera movement
• Removed test_world

If I waste so much time just to create tutorial level... How long it would take for me to create 5 puzzles?
