Finally, some useful feedback. Thank you so much.
We wanted to keep killing enemies only for the Hero and tried to give rid of the Hero being stuck in one place. We added spawning enemies to different direction than corpses were from the player, enemies avoid corpses to some level, but as hard as we tried there still will be some moment when Hero was stuck.
Maybe some weak attack for the Garbage Collector or some other way of getting potions would be useful.
