Tutorial & Sound v1.2

This update took a bit more time than usual. I mainly improved on features focusing on accessibility and ease of use. I wanted to nail the feel of the game before adding more content to it.

• Additions 
  • Tutorial at the start of the game, also accessible via menu
  • Custom bouncing sound
  • Ability to adjust  post processing and sound volume via menu
• Changes
  • Tweaks to animations
  • Changes to platform generation to improve gameplay
• Fixes
  • Fixed player sometimes not slamming down when above platform

I'm going to add a points system with upgrades the next update. As well as fixing the many issues I've encounter but decided to ignore.
