I want to compliment the excellent cold open, where the already-loaded game lines up well with the itch page's background and is just waiting for you to throw the first dart before sliding in the menu.
Near the end the engine kind of breaks, with the darts despawning almost immediately, turning the massive shower into a pulsating core, as the sound effects go so rapidly they blur into each other. But I suppose that's part of the experience.
