Quick update

Since the GMTK Jam is over, I wanted to make an quick update to fix some problems.

Changelog:

• Leaderboard is fixed in Web build.
• Added a new weapon - Ray-Gun.
• Balance fixes aimed to make Shotgun and Rocket launcher more viable.
• Dash is improved and now goes through enemies.
• Added the Upscale and Downscale upgrades, a system that I’m quite mad I didn’t come up with during the Jam itself.
