[*]Achievements should now be working for Mac editions of the game. [*]Unfortunately, as a part of this fix we've had to reset progress on cumulative achievements such as "Upgrade Ship Speed 100 times" or "Collect 250 Power Ups" have been reset. We apologize for the inconvenience. However, achievements that have already been unlocked have [b]not[/b] been lost. [*]Bug Fix: The conditions for "Destroy X number of enemies in a single play" achievements now [i]actually[/i] require being done in a single play whereas before they were a cumulative counter across multiple plays. [*]Bug Fix: The background music on the second boss now plays the correct track.
