Cool idea, however I was completely lost for a good bit. While you do have a "what to press instructions" on the fight screen, you're missing the "how to play" part, even just a description on the game page would be good enough for a jam, as not everyone has time to make a full tutorial in-game. That said, a very unique idea, even if I couldn't get the dominoes to "domino" that right way, I just dropped them on his head! Nice idea and awesome voice acting!
I also played this on stream, in case you wanna see: VOD timestamp for your game. ^_^
