This update mostly focuses on some textures which have been remade or changed to look cleaner, however it does include a lot of other stuff too!

Changes / fixes:

• Bullets will pause and resume motion when the game is paused/unpaused.
• Smarty (you!) will pause and resume motion when the game is paused/unpaused.

Additions include:

• A single music track to play on all current levels, more will be added over time.
• Third new level!
• Tutorial now includes instructions on changing bullet type.
• Added credit to music used on main menu :)
• Main menu includes a static sound which will distort, and eventually stop.
• Many secrets...
