First off: high five for developing a tabletop game! Im a big fan of D&D, so this was really cool to see. Really enjoyed the seeing a dungeon creator. Lots of charts and options. Were you inspired by D&D at all? Or did you take inspiration from somewhere else?
I do enjoy the encounter generators as well. I think it would be awesome to see more details that could be added to the dungeon. For example, after adding the main structure, you can roll to add in secret doors, water fountains, or other architectural features. Would you consider making you own ruleset for D&D? Or possibly integrate it with the current version?
Very excited to see other tabletop enthusiasts and this was great to see!
