The visual style here is awesome, feels very avant-garde, obviously carefully handcrafted. The gameplay is very simple but somehow still satisfying (the smooth animations definitely help there, very satisfying!). The sound design is also really good; any game where the music responds to the player's actions immediately pulls me in. The best part, for me, though, is the opening menu transition; I was not expecting that, and it kind of blew me away. Really cool stuff all around.
