A nice looking game that is easy to understand without any in-game instructions (although that would be good later).
As a prototype/demo, it is quite polished and playable.
You said you would like comments:
I did find that using the blue circle to move between the 3 people in the village was a bit disorienting. You could point at the circle next to magician and end up with your back to him when you teleported.
Physically throwing items was a nice idea but after a while I felt it started to get a bit monotonous and I wished there was another method (to mix it up).
Maybe it was because my arm was getting tired having played it a few times! That could be helped by having another column (near the portal?) so you don't have to throw the objects too far?
I tried using both hands to pick up objects from the crate but it only seemed to allow one at a time?
Can you move the position of the crate so that it is always on the edge of the column, between the player and the monsters? On some of the columns you have to keep turning around to grab an item then turn back (or have to point the controller behind you).
Maybe the accuracy could be more lenient? Sometimes I thought I had hit a monster but they never reacted.
