I finished the game yesterday and I hope you can expand it in the future. I may have some ideas that I can throw at you.

Read the papers by Brian R. Pellar published in Sino-Platonic Papers. He has the theory that the Phoenician alphabet (and by extension the Hebrew alphabet, Latin, Greek etc) are derived from zodiac constellation asterisms.  The major arcana cards already are connected to the Hebrew letters and zodiac constellations. Pellar's theories are more scientific and original, so they may not fit with the standard traditional tarot interpretations. You have a puzzle with runes, so maybe you can add a Phoenician alphabet or Hebrew alphabet puzzle :) 

Also look into The Grand Lenormand (Grand Jeu de Mlle. Lenormand) for more alchemical, mythological and zodiac connections. There is also the The Mantegna Tarocchi. It's true that all these tarot decks are very different. 

This is more for a possible future project, but you can read Romanian Peasants' Beliefs In Stars & Sky by Ion Ottescu  (Credintele taranului roman despre cer si stele).  You can see the Romanian traditional constellations in Stellarium. Maybe you can do a puzzle game using Romanian traditions :)
