Thank you for the review, DeadZergling. I noticed some bugs that hadn't shown up in my playthroughs and it appears some of the key functions aren't as obvious as I thought they were. There's an auto-target function for melee attacks that characters can toggle on and off (mentioned in the chicken tutorial and in a tooltip when mousing over your abilities), but it snuck past unnoticed and I really need to make sure folks don't miss that or they'll have a hard time like you did. (Using the auto-target, everything becomes less grindy as you can more easily cut through enemies with melee attacks. It's also a lot more enjoyable than throwing your hammer over and over and over again.)
I've tested it with a couple of friends a few times and they definitely say it's more enjoyable played as a group, so feel free to test another dungeon with friends and using the melee auto target ;-)
Thank you again!
