Thanks for the feedback! We wanted to be a bit subversive with our character, and what's more contrarian than a girl in a sun dress wearing a football helmet? We never got around to getting the narrative in for the jam, but the gist is that you're following in the footsteps of your friend who is something of a sports jock.
There's definitely a common theme I'm seeing on the feedback about the movement - we certainly have issues that need to be addressed. Specifically about how potions interact with movement, I know something really funky is going on - if you hold down your movement keys while drinking the potion you may be able to just zip along the dungeon. Which, while entertaining, certainly isn't intended. We've also noted the issue about picking up stacked items - I'm not exactly sure how to deal with that because when the items occupy the same location there's no way to be sure which item to pick up. I suppose we'll need some additional selection in order to make sure you're picking up the item you intend, especially given that picking up items costs you a turn in combat.
