version 1.3 updates

Thank you to everyone who downloaded the game!  This ended up getting more attention than I expected, so please let me know if you are running into any problems hindering your playthrough.  This is a small update to make some improvements in the experience:

1.  From watching playthroughs, I noticed most people are missing the conversation with the pier attendant.  He was hard to see before, so I added a little lighting to help out.

2. Some people have said the mouse sensitivity is too high, so I lowered it.

3. I added some extra collisions so that your potato gun behaves more realistically.

Hopefully this doesn't introduce any new issues!
