I can see me using this as is for one of my groups. It is internally consistent with flexible starting conditions thanks to your tables.
Four things: 1 Where are the toilets? They are described on bottom of page 3, IIRC. 2 Are toilets also at the two symbols in the secret room on level 1? 3 I like your use of coloured dots to show NPC locations. In the future, consider augmenting those with other shapes (e.g, square, triangle) so color-blind users also discern the differences. 4. The description of the body dumping site on level 3 uses “below” when I think you mean “above,” though perhaps I am confused by the elevation or orientation of the levels.
Thanks again for the excellent dungeon. I can’t wait to see if my players will smear their blades with peanut butter!
