Not a fan of how the dungeon tiles can appear rotated from how they are on the cards. It took me a while to figure out tricks for traversing the dungeon, especially because where the doors are on each tile matter so much. It makes reaching certain areas a bit of a chore if you don't have cards with doors in the right place. Could the doors be made more lenient, i.e. adaptive to what tiles are around it?
Nice concept and aesthetics, though watch the legibility of those coloured numbers!
