The music and sound is absolutely gorgeous, and the art style is lovely. The game mechanics are simple but very intricate, I could actually feel myself getting better and faster with every level, so the difficulty feels like it naturally escalates, except for a few spikes here and there (like a level in the middle being harder than the final ones), but other than that the difficulty felt perfect, if not on the harder side. When you die, you mostly feel like it's your fault, which is a huge plus. All in all, a lovely and very charming game.
