I'm actually considering buying the whole pack that's how good this is! Anyone who likes the type of game where you reveal the board as you progress will know what to expect. Not much detail but I'm fine with that. With just 6 tile types the dungeons you can make are endless.
The pdf isn't worth it in my opinion, its locked and can't be worked with. However by going to the makers website you can use the file as intended. 2/5 stars only because of the website.
Justin, could you describe the specific problem you were having? I tested the pdf on a number of setups and it always worked, and I'd like a chance to troubleshoot the issue you're having so that other customers don't have similar issues. However, I'm glad the online version worked for you!
