v0.957

The 7 Day Roguelike challenge approaches so I must set aside SAD GOD for a bit.

Thus a quality of life update:

• The shot icons have been redesigned so they look like unique symbols.
• There is a sound toggle in the main menu, this should suffice until I figure out a general options menu.
• The ghost now spawns every 11th shot. This is reset when the dark is off-screen and during boss fights. Slimes can still spawn during boss fights if you get near the dark, I think this is fine.
• Some adjustments were made to various chunks that had issues.

Work shall resume when the ritual is complete.
