LD34 - Fun with magnets!

This is my entry for Ludum Dare #34. Your goal is to lead as many balls as possible into the "deposit" area by using a magnet. You can control the polarity and activate/deactivate the magnets movement along the bar its attached to. Beware of obstacles and specially wheels, that can destroy balls (however, theres only one at the last level and you may beat it if you only lose one of them, so this warning will better apply to a hypothetical post-compo version). The game should be playable on mobile devices. At least Ive tested it on a Nexus 5 using Chrome. >>>>>> Controls >>> Keyboard >>> Mouse/...
