I agree gold might be a little too necessary, but thats pretty common in most card games (read: magic) The UI could use some work but overall its a good game. You should maybe add a redraw initial hand at the cost of redrawing one less card, for when you get 0-1 gold mines.
I agree with Orzo on a few points. While the new ability for Team focusing is nice, I found myself using Relentless and Phalanx solely as I would using the character myself. The only difference is I couldn't actually pick the ability I wanted, such as Roald's stun or Veradux's de-buffer. Misses are extremely frustrating when Legend Running, usually making or breaking the fight, I would reduce their chance or perhaps introduce talents/gear to remedy misses specifically, rather than a side-benefit of high speed.
A few hints for 14 for those who don't want to use a whole walkthrough.
The metal ball will knock down the two left facing fans.
There will be 3 fans on the left powered branch to start, but 4 at the end.
Try to make sure the middle branches are never powered (they can be briefly powered, but too much and you'll knock off the finish)
I just beat a queen, it said I got the key, and I got three other awards at the same time (1500 nest score, 50 deflected hits, 5 dodged/parried queen attacks). I did not however get the key in the end, as I cannot unlock the sword >< any help?
