WIP HTH Unity: Update 4: Sapphire Cave (Patreon)

1. A cave entrance near the Visitors center. An interesting side detail, This is the first time I've had an external map link to an internal map. It's very basic, tons of games have them but this is our first. ^.^

2. Looking inside, the cave goes quite far, I'll avoid any spoilers.

3. Some details: Crystal, plants, and glowbugs

4. Bioluminescent algae can also be seen in the water
