Version 2.0

Game jam is over and I've release some improvements. This should make the game much better. 

• Coins picked up by simply hovering over item.
• Optimized code. Should run a little better. 
• Calming music has been added.
• Rebalanced coin values and upgrade costs.
• Reorganized how upgrades are unlocked.
• Flowers now drop coins. 
• Nerfed the witch.
