Enjoying this a lot so far! Found a bug that breaks a cycle though. When fighting a goblin horde, I misclicked and queued up a goblin fight and a random rat fight at around the same time.
When the fight with the rat ended, I was back on the menu with no option to fight goblins, and no way to advance. Thankfully with that reset cycle button I can still start over, but just figured I'd make sure you were aware!
