I was just about to post this, damn you.
Many might know Edmund
McMillen as just the Isaac/Meat Boy guy, but the weirdness of his works also extends to him as a person. He's a superfan of outsider artists, often ones with mental or physical disabilities; the more deranged and out-there, the better for him, and that most definitely includes Chris. He's remained a fan of Chris even after his incarceration. It's also likely he has gotten Chris to voice a cat in the game (Mewgenics is going to have many vocal cameos by celebrities, and Chris is likely to be one of them). Definitely something to follow closely if you're eager to see what Chris is up to.
Here's one of his
TikToks about his CWC merchandise, as an example.
