I'm glad to hear you like it! If you want to play it solo as both the adventurer and the dungeon's ghost it holds up pretty decently, although that wasn't my initial intent.
If you make something with cards in the future (they're great to hold in hand and stockpile, they have that physical presence you can't quite get with just rolling dice and writing down words on paper), I can advise to make both printable sheets and folders full of individuals cards, which would be roll20 compatible (and maybe other VTTs). That way you can play it online, which opens up more opportunities to play it.
I'm working on other stuff rn but there's good chances we will see an update! Expecially because some things need balancing.
