I lost my sword right in the first room, Strong Magnetic Field, and immediately thought about restarting. Good thing I kept going, because right after that I got lucky and picked up a Fireball, which let me one-shot my first enemy, the Minotaur. I really did need that luck, since I got his Axe afterwards. I've now visited 19 rooms, a whole lot of Bath Houses, and hit my first level-up.
What I'd like to know: do you just keep playing until you die, or is there an actual goal? Because the enemies don't really seem to be getting any stronger, do they?
