I've stayed up a bit too much adding stuff to this thing. From the original version (1.0) I've added music to the main menu and the main game itself. Although I may change the main game music, all credits to Garrett Williamson (his site: garrett-williamson-music.com).

There's also minor changes:

• Main Menu Button when you die (will add a pause screen eventually)
• The error obstacles no longer keep moving after Tux dies, so you won't get an extra point after hitting a top error obstacle.
• A mute button at the bottom left, in case you get sick of the music (happens eventually)

Features I want to add:

• A pause screen
• A proper Tux sprite with flapping animations
• A death animation for Tux
• UI revamp, rather than having basic buttons/fonts
• A coin mechanic
