    ChaO delivers in that it spans a wide range of genres and makes you feel a spectrum of emotions in the span of an hour and a half. Its unusual animation style makes it more memorable, since it doesn’t look like anything else out there and will be remembered for its extraordinary, one-of-a-kind aesthetic. It also helps that it’s hilarious. https://bit.ly/MermanChaO
