Demo bug fixes and polish

Huge thank you to all who have played and left feedback on the Demo so far!

I've been constantly working on improving the experience and these are some things I've done and bugs I've fixed:

• The boss now has music and SFX! :o

• It's now possible to descend ladders, whereas before you had to fall down and take some fall damage (:

• The basketball obviously was a big frustration to a lot of players. So I've added a dialogue, that if you miss a couple of times, tells the player to come back when they learnt how to do it.

• I also made the basketball easier to score, when you actually know the way to do it.

• I polished some collision to prevent getting stuck (Still lots to do but working on it)

• I added a little more guidance and dialogue to lead player on the way on the first objective.

• Addressed a bug where cop would trigger a dialogue every time you stepped into his trigger, becoming very annoying.

+ A number of minor fixes.
