12/01/2014: Small speed improvement by making horizon into a sprite.
30/12/2013: Improved framerate by making physics timescale dynamic. You can now press R to restart!
Make sure you don't have any other projects/CPU intensive things (like twitch streams) open while playing, or the game will be broken by lag spikes!
If a lag spike occurs, your best bet is to attempt to slow the ball down as it will keep going as the game attempts to redraw the level.
