Alida

Alida, a guitar shaped island off of the Australian coast, was built by members of a musical group who sold enough from their first album to make its members extremely rich.

When no second album is produced they're all but forgotten by their fans. So the band split up, each person taking up a separate area on Alida and hoarding their remaining money in elaborately locked vaults. After a time, all of the members of the group left the island. Arin, one of the members, goes to the island for a supposed reunion but has never returned. His wife asks you to go to Alida and find her husband.

You play in first-person, Myst-like solitude. Explore the entire island to figure out what happened to the band and to find Arin. The puzzles range in difficulty and most are musical in nature.
