1. Agreed, that would be very helpful to players who haven't memorized the map.
2. Agreed, I will fix that in the next update.
3. Kinda have to disagree, because that's part of Joe's character mechanic, although I do agree that it's a bit annoying, so I'll slow him down in the next update so the player has more time to decide what item they want to give up if their inventory is full.
4. I won't be adding any items from BB+ as I want most of the items to be custom.
5. Interesing idea, but if i did something like that it'd probably have to be capped to 1 item per locker, so it's not too overpowered.
