Tiny update for Mail Runner

Hi there!

Just wanted you to know that I've made a little update for Mail Runner. To play the updated version, you will have to either download it or play it on the game's lexaloffle BBS page, because I want the browser version to be the jam version until the rating period is over. Hope you enjoy!

Update log:

• Evil shadow is less annoying
• Lightweight is even lighter
• Added high score
• Slight changes to level design
• Added some more fx and sfx
