This might be a bit long winded so please bear with me on this.
I'm sorting out the marble problem in the golden dome, I've sussed out the relationship between the symbols on each dome, the 3d imager on map island, and the way the colours relate to the symbols, however there are 6 colours but only 5 islands, one of which is prison island which so far I have not been able to get to, (I managed to get to Moiety but came to a swift end when the credits started to appear but that's another story).
Also the "sight" for the dome on map island is bent so you can't see the aymbol when the dome stops.
In a nutshell have I got to get to prison island before I can finish the marble puzzle.
Onwards and upwards.
