Thanks for the detailed descriptions. It helped me fix both of them right away. Though I couldn't replicate the freeze with the overencumberance, I made it so you can no longer start the dungeon overencumbered. I plan to allow you to upgrade the encumberance limit (and have certain classes (e.g. ponygirl) increase it as well) in case you want to take "decent" provisions with you (i.e., buying up more than half the shop).
lost my hero in the 2nd dungon, went on a new mission and got overlapping enemies. looks ridiculus, but somehow its an adoreable animation.
