I think putting a match two and dungeon together is a really neat idea, and you executed it very well here! My only note is that having to click on doors a certain number of times in order for them to open made it feel a lot slower, and since there wasn't a visual indicator for that, I would often find myself unsure why a door didn't open. What you've got is great though, and other than that I can see that a lot of work went in to this, nicely done!
