Main comment from me is that I couldn't get to the end because of the combat.
Now, to be fair, my potato laptop with integrated graphics was occasionally giving me some lag with camera movement (for the camera I was controlling via a touchpad...).
However, unless I missed something, by the time you're getting swarmed by enemies in the castle, you've only been taught a simple smack that's good enough for boxes.
I tried some buttons at random; but I couldn't find something like a dodge or dash that would let me avoid damage.
However, given the focus was the pick up and carrying of items, I would call this good progress and a success for the jam.
The combat felt a little clunky; but the pick up, put down, and switches all felt very smooth.
