Hey this looks excellent! I think I possibly noticed an error? On page 6 under Turns it is stated that players may "take one action (...) and make one movement before any and all opposition do the same". My understanding was that everyone's actions in Into The Odd/Electric Bastionland were simultaneous? The second sentence about making a DEX save to act first would also support that.
That wasn't my interpretation of the rules. I think it's clarified a bit in the newer version of Into the Odd. "Generally the Players take their turn before any enemies. If there is a risk of being surprised, characters must each roll a DE X Save or be unable to act on the first turn. On their turn, Players can act in any order they wish."
