Wow great concept and the title gave me a chuckle.
You really love your tarot cards, haha.
I was able to break the game on the third attempt. I was already on island 16 or 18. I had 4-5 queens and a king. I was stacking a lot of extra turns, sometimes reaching 5 turns for a single piece. I had reached over 100 souls. The last thing that I did was rearranging my cards before leaving a friendly island. As I pressed embark some of my pieces disappeared and the game froze. (web build)
Still - had a good fun. The tarot upgrades make for some unusual puzzles with the enemies. Some of the upgrades are more troublesome than others. Does the difficulty progression account for that?
