I really like a lot of things about this entry. I like the implied fantasy setting. I like the verticality of the space. I like the pregenerated characters (kudos for harking back to old White Dwarf material). I like the colours and presentation. I like the original choice of hazards and opponents. I like the sentiment of the adventure.
Its a great piece and one of the strongest things you've written - the jam really brought the best out of you. Well done!
