The idea behind it is cool, though I don't think it works well for a "puzzle" game. The results of dice rolls are random, though you need specific ones in order to proceed, so instead of an actual puzzle it's rather rolling until you get the correct ones (which might take a while, since it's random and the spawn points are quite far, so it only adds to the padding).
Don't get me wrong, I don't think it's a bad game (by all means it's not!), I just don't dig "luck based puzzles" :)
