Awesome game, a fun waste of time! I had a fun run of the demo all the way to the end.
I had one unfortunate point, though, where I was looting one of those one-off chest loots and I had full inventory. There was a nice blue gold ring there and I wasn't able to get because I couldn't figure out a way to discard items from the inventory to make space (if that's even a feature?) and had to leave the rest of the loot I couldn't pick up in the chest. When I returned, the unpicked loot was gone, from which I assume the chest was flagged looted.
I would say the key feature missing in this interaction was the inability to discard items from the inventory if I'm not mistaken about its inexistence.
