The best platformer. Period. A deceptively simple-looking visual style pairs beautifully with impeccable sound effect and song usage to create the closest thing to a flawless atmosphere I think I've ever experienced in this game. The gameplay incorporates some super interesting (albeit at times a bit buggy) gimmicks that are intuitive but don't baby the player. This combined with the aforementioned atmosphere creates a truly special experience. Plus 1374 being in the credits as a playtester and bugfixer proves that they're alive, which is an added bonus.
