I suspect it was because I did not play it in full screen mode--at a certain point around the beginning during my first run, enemies would be all over me and when I used the breathing attack and timed it correctly, it would go off but wouldn't hit. But that only happened once and the rest of the time, the game played great! I really enjoyed it and I love the aesthetic and sound track! Every other time I played it, I played it in full screen and it played perfectly. Tbh I'm not sure if there is anything you can do about screen related issues like that but just know that it did not affect my rating (I gave it 5 for all categories)
