This is a really cool take on the match-3 genre! I really liked that you included traditional dungeon elements beyond just monsters and chests and stuff - but scenery and props as well. I also liked that it's not just a case of matching identical colours, but of seeing opportunities above and looking for matches with those.
Beyond that the art and music is just really nice. Especially the backgrounds in the title and ending. The muted colours with quite detailed shading is not something you see a lot at low resolutions, but it works super well!
