Hi, I didn't get to play the game but read through the rules. It looks very thought out! Am I right to assume you didn't draw the characters yourself? If you did that would be very impressive because they look awesome!
Couple questions I had: When is the game over(kill Bob?)? What is Bob's power level without skeletons? 0? 1? How many cards of each category are you supposed to have(is it just infinite/randomly assigned)?
Not sure on the 2 player aspect as you don't seem to be against each other and if you need to help each other then from what I can gather you can just kinda build a strong team by yourself by doing the quests and ignore the other player (also if they are downed?). Again I haven't played it so maybe this is nothing but more interaction between the players might be good.
Anyway I think it's not too difficult to understand which is good and I guess you can really get stronger with your characters as it goes on so that seems like a lot of fun. The quests are a fun way to force everyone to move around the map. Also dice are always fun haha.
