i toyed with this concept for about a year (on and off) and finally found a gameplay which i think suits the visuals i had prepared.
the current prototype took me 4 weeks / 200 hours to create. still the gameplay features a few cards which are a bit complicated, and the game lacks visual effects. also visualization of player reaching goals has still to be added.
i'm pretty sure i can release it in 2013
if you are interested in trying it out on android - just mail me!
