Postjam update (v1.1)

Thanks to everyone who played Sacred Scales through the GMTK jam! Here's a post jam update following some feedback:

- Increased score needed to win the game, making the game a lot longer

- Scarabs spawn faster late in the game

- Decreased size of left 'shelf'

- Increased every item's weight slightly

- Statues spawn slightly more often

- Feathers spawn slightly less often
