Yass! Tabletop games are awesome! I am also a great fan of D&D! I definitely was inspired by D&D and tried to homage it in several of the monsters and items. In the first draft there even was a way to cast "Sticks to Snakes", but I had to remove it when i revised the treasure tables.
It was really fun writing the encounters and adding little details and flavour to them wherever I could.
It would be really fun to add more features and content to the game, like additional structures, dungeons with multiple levels, differently themed dungeons, more encounter tables etc.
Integrating this into DnD might be difficult, mostly for balancing reasons. It would be hard to make it such that all these encounters are an appropriate challenge for a Character.
