I like the Mac aesthetic! The alternating white-and-black squares are a bit harsh on the eyes when moving orthogonally, but maybe that was normal for the Mac :)
I have a few suggestions:
* A message to say when something has been picked up would be useful.
* When selecting a wand from the inventory, you have to then close the inventory before you can use it, but there's no guidance for this
* The teleport wand says "Select an enemy to teleport", which is inaccurate as the wand has to be fired at the enemy.
