I like the feel of this a ton! Especially satisfying to figure out how the maps work, and how to use the info/numbers they provide to start making better, smarter (safer) exploration decisions.
And then even more satisfying to backtrack, once stronger and more confident, to find and tackle the earlier wardens and collect their rewards.
It does however leave the feeling that this current version has not much new to say after the 5th floor.
And then it seems to *really* have nothing new to offer after the 11th floor.
I kept going for a while (through floor 20!) on the strength of those initial discovery feelings, but I probably would have appreciated a notice that there wouldn't be anything further to discover (or, of course, an ending) well before then.
But I really liked the initial feeling of this. Nice work!
