v0.3

> Added basic Main Menu
> Obstacles now retract to bottom after reaching top most point
> Fully randomized obstacles
> Added basic scoring based on time

Bugs:
> If you stay on the top left, you will never lose
> Collision still erratic. Problem in collisionCheck() function
conditions, most probably
> Obstacles going back down are visible. Should disappear, then reappear
on the bottom

To Do:
> Splash screen
> Maintain a high score
> Build leaderboard
> Graphics
