I'm pretty excited that I just randomly found this, I love a short and sweet adventure that can easily be dropped into a campaign. The descriptions are all super usable, straight to the point, and the artwork is just the right amount creepy and charming.
Have you considered making a version for a more typical retro-clone/D&D adjacent system like Old-School Essentials?
Unfortunately, I'm totally ignorant to His Majesty the Worm, so it'll take some guess work on my part to come up with stats based on those symbols in the monster sections.
Thank you so much for your kind words. I am really glad you like my dungeon.
There are currently no plans, but it might be nice to include some Cairn or B/X statblocks if I ever decide to release it for print.
To take away the guesswork, the stats are Strenght (Swords), Dexterity (Pentacles), Intelligence (Cups) and Wisdom/Magic (Wands).
