Really fun! I love the intro, especially the sword =).
While playing I kept pressing Escape trying to close the inventory, I wish it would do that =). Inventory has some (presumably well-known) issues that were frustrating (couldn't swap things around without dropping something / making space, couldn't use things from the inventory, had to unequip weapon, equip potion, exit inventory, use potion, open inventory, re-equip weapon, which was really cumbersome).
First run I was killed by a rat on the other side of a door that I didn't notice :(. It would be nice if it would have restarted me at the start of the floor instead of back to the beginning or something, but it didn't take too long to do the first floor again, and then I was much more careful of critters on the other side of doors =).
I made it to the end, and loved the little final animation, that was nice!
