Having your inventory scale with your health is an interesting concept. Forces risk management. Having the enemies attack each other was unexpected to see.
Was it intentional to be able to play without picking up the cursed backpack? I tried that on my second play through. Certainly harder only having only 1 inventory instead of the growing cursed one.
Clicking further spaces to move towards that direction could be helpful. It would be nice to see inside enemy backpacks while wearing the cursed one to take the items would add more to the inventory management idea.
