I am a fan. Multiple realities, mirrored dungeon, simple ye differentiated layout makes it trivial to understand and read, and the dungeons distinguish themselves from each other. I love the continuum of science-fiction - science-fantasy - fantasy here. The possibilities to move to different realities really spices it up. If I could offer one critique it would be to remove some of the labeling from the map as it adds clutter, The colors, drawing, and keys already did that work for you very clearly. Excellent work!
