v0.2 - Leaderboard

Heya, 

With Unity 6 out now, I decided to finally fix a few major problems with this game. Most notably, Akio now has a global leaderboard, meaning that your runs are synced accross players.

Other changes:

• fixed bug where player had infinite lives
•  fixed bug where timer reset when going back to checkpoint
•  changed credits 
• changed start and menu
• WebGL support
