Post-jam touchups

A quick update to fix some visual stuff mostly. Also, I managed to get the web build working so that is live right now.

Changelog:

• leaning now slows you down more but you regain speed when going back
• lowered the max speed
• made turning more forgiving
• made the game resizable – this is to prepare for the android version which may release at some point
• put the charge meter at the top
• made the buttons look a bit nicer
• added animation when making new circle
• items now slowly fade out
