Get The Gems RELOADED - Small patch

Greetings cave dwellers!
I received feedback from several players that Cave 5 was a bit too hard.
I therefore took a closer look at it and made some changes:

• The number of gems needed was reduced from 100 to 85
• The available time was increased from 400s to 580s
• Several crabs had to leave the cave

Happy spelunking,
PSY
