Run n' Gun bugs fixed and timekeeping added!

Small update for now, but more content coming soon!

This update is mostly just a bunch of small fixes to the game which have been bugging me since the jam finished.

Changes include:

• Volume slider for music works with all the songs now
• Best times for completing levels are now saved and are displayed on the level select screen
• Timer only begins when you press a movement key or use the grappling hook
• Added a quick restart button (R)
• Made the end zone (the goal of each level) have a larger hitbox vertically

I plan to:

• Add more levels
• Add enemies that might actually pose a threat
• Add a few quality of life improvements
• Rework the dash (currently its not very useful)
• Generally polish the game
