Agree with pretty much all the comments below, especially the positive ones! Also want to add that the movement interface--dragging a die to the location, with the indicators for where the legal moves are--is terrific. When I started, I was afraid it was going to be a very tedious matter of picking a die and then using the arrow keys to move, and instead it was this excellent streamlined action.
I also agree that there's a lot of interesting space for expansion if you want it. More types of dice! More types of enemy! Heck, more types of adventurer (the rogue, who gets arrow dice instead of attack dice, that launch an arrow in the direction to kill a monster but doesn't move)!
And I agree with the "a lot of waiting" comment. The monsters were slow enough that avoiding them wasn't very hard at all. And once you've cleared out the monsters, there's a lot of "I need a 1. End turn. End turn. End t...there we go". The main thing I'd want to see added is a "zip to exit" button once the monsters are cleared--you can still walk around and collect the coins if you're so inclined, but especially once those are gone, getting to the exit is merely a task, not a (particularly interesting) challenge nor even something you can fail at.
Overall: very nice!
