since you are giving us an action key (F), i expect to be able to close the tutorial dialogue boxes with it as well.
esc should also be able to close them. indeed, esc should be able to close lots of other things, like inventories.
took me a long while to understand how to equip spells
i didn't personally enjoy the entire stagger meter thing with common enemies. they just spend a lot of time helpless on the ground while i kill them, slowing down the pacing. i'd say give weak minions less health or shield
the boss rush you had before felt more climatic and satisfying
lots of typos and some engrish in the dialogue, which is a shame because the eye guys seemed pretty funny
