Phew! I got through the demo. This took me a few hours, mostly because of the maze level. I spent most of my time getting lost and running in circles, when I did find the end boss I was over-leveled for it (also took 2-3 hours before finding my first ADDI server) :)
In a full release, I would be hoping for two things: having a system to mark tiles you've been to, like dropping a marker or bread crumbs, and extra decoration to help players distinguish where they are better.
I'm very much looking forward to the full game, I had a lovely time. Cheers.
