Well... On a short little play session, I've noticed a couple little things:
1) The tutorial (which I'm sure isn't finished) needs text instead of just blue squares, in my opinion.
2) The signs in the BAAdlands (in my first session) all spawned the same message, save for one.
3) Aesthetically, dungeon walls when spawned don't always close of at the edge of a map, making a path to nothing (just a slight nuisance).
That's it for now; I'll look for some more later. It's really a wonderful game, though!
