Very cool game! There ae a few bugs with the followers and there sprite sheets (i.e. the followers not following you and just standing there stacked on one another) but overall I really enjoy it and it's premise. It's nice to have plenty of choices for followers and the opening crawl was a good set up for the story.
My only suggestion would be to keep building on the dungeon crawler aspect and add some different puzzles/mechanics to get to the next floors (i.e. needing four pieces of a key from different enemies, having to defeat all enemies on the floor, needing to revisit a past floor).
Excellent start!
