The Enigma is a puzzle game that is mostly inspired by Spych.
The overall gold is to complete the level with all available diamonds on the level. To get these diamonds you might need to move some of the rocks that is in your way. But be careful - it is possible that they might be in your way later on in the level. Futhermore - there are doors that can only be opened if you have a key - also... use them prober!
