ok a few problems with your greek mythology. Firstly atlas is a titan and he held up the SKY not the earth. As for the boatman, its two coins on your eyes, not one under your tongue. The one under your tongue is egyptian (I think....).
Just recently I discussed the midas touch with my physics teacher (who also read mythology) and we came up with this as the first problem: the mass. Matter can neither be created or destroyed, so either the gold is basically painted. Otherwise it would have to shrink in size, or the air around it would be converted. So why doesn't the air around him turn to gold? Anyway cool game.
