This would be 5 stars, 10/10 if it wasn't for the fact that the game SHOVES ads and it's ridiculously expensive subscribtion service in your face after every death, level and every time you run out of stamina. It's a shame because the gameplay is absolutely phenomenal, the artwork is slick and the sound effects are great. I've made it to around level 35 right now and the difficulty progression has been increasing nicely through each level. I do hope they eventually tone down all the ads
