A fun puzzle game that's more of a card-game rather than a roguelike.   Well balanced. It maintains that threat level while giving the player a way forward.  The transmutation loops you can make from your choice of upgrades has a nice long-view strategy aspect to it.  I never did manage to transmute gold. 

Really interesting and deep! It took me a second to get a hang of it but now that I have there is a lot to keep me trying to get better. Also, the graphics are pretty cute. The only improvement I can think of is adding a way to view your deck so you can remind yourself of what cards you have with what combinations of symbols to help prepare for possible upcoming cards.
