I tried your game here on the itch.io page.  I found it frustrating that there are rooms on the grid that, when I entered, would immediately collapse, killing me under the rubble.  It isn't that I mind environmental hazards, but there is nothing at all (that I could see or hear, at least) that indicated to me that a room might be unsafe.  It feels "not fair," in a rogue-like/NetHack sense.

I do love the graphics.  I'll check back on the game soon.
