Rightey,
here's what I've worked out so far (from what I can reach in the demo - thankyou, PayPal

) with respect to the Aquarian runes throughout the game. It's fun working it out,
so don't refer to this unless you really don't want or intend to work it out yourself. My guide was thrown together in Paint, and has none of Derek's artistic flair

, but you should be able to interpret inscriptions reasonably. The remaining undiscovered letters should be pretty obvious when they pop up as there are so few, but I'll update it when I come across them...
