So right off the bat, pretty interesting premise. I'm not really one who is all that familiar with dominoes but the concept of using dominoes to fill out an expansive dungeon full of monsters, traps, and special locations brings back a lot of fond memories of playing "Betrayel on the House on the Hill" for the first time, only this time everyone knows who is dead before anything spooky happens.
The mechanics are very simple to get a grasp on and every crypt feature listed gives a brief description that properly conveys what the feature actually does. Every crypt feature adds a new dynamic to the dungeon and how players are expected to progress and the nature of the game allows every playthrough to be unique, adding to its replay value.
The visuals are cute, distinctive, and well drawn. The text is neatly organized. I love the thick black outlines used all throughout for the characters and images for the crypt features, and each image offers a lot more detail than you'd expect for the art style, such as the images used for the [thief] and [scavenger] symbol. The only gripe I have with the art is that some of the art is off-center a bit and sometimes the text wrapping effect causes the image to clip a little bit into the text, but these flaws don't hurt the overall quality of the visuals, which is well above average.
Overall, an excellent entry that I would highly recommend to others to try, if only for the mechanics and the aesthetics alone.
