MANY UPDATES! NEW ENEMY + SYSTEM CHANGES.

A lot of small updates in this round.

I'll write more about them soon. I'm tired!

• New level up system
• MP is consumed in new way (Now refered to as Moon Power, for my game)
• MP is restored every night at midnight
• Enemies respawn after 24hours (in-game-time) 
• Shield animation upgrade
• New Alien enemy 
• Lots of optimization to the overall gameplay
• SWIMMING TAKES AWAY HP UNLESS ON THE SURF BOARD
• Most things work better now
