Thank you so much for the feedback. I am looking at ways to extend the experience into more floors with more interesting challenges, but I think for a 7DRL, a single dungeon is doing the job :)
I need to consider the final goal. Defeating every enemy isn't a particularly roguelike activity, but that's how you progress your character's abilities, so quite a dilemma.
I'm really glad you had fun playing it, keep an eye out for future updates!
