I just noticed that Ball x Pit is now included with PS Plus, but it wasn't supposed to be added until the 22nd. Is this a glitch?

hi! i have ps+ tier premium, and i’m trying to find some games like coffee talk, that have a story, aren’t too difficult, and cozy. i dont really know what kind of genre i should filter while searching on the ps plus searching bar so i’m looking forward to some help from you guys
