I like that you included a bit of an intro cutscene, helps set up the context and give it a tone of your voice. It feels like a very original concept, and shows promise. In its present form I didn't click with it, but I can see the amount of thought that has gone into the design of wanting the player to consider their movement in relation to the attack/abilities they can pick up depending on the numbers on the dominoes.
That level intro animation where the pieces all pop up is slick! With all the moving parts working, it shows a solid proof of concept that warrants further game design and balancing. I had an instance where a bunch of sixes were just bunched up around my starting position, so I used that lightning skill repeatedly without worrying about the enemies, it was a novel moment and I felt powerful if not a little overpowered haha - that moment of identifying an area I could exploit was a good one.
