It's fine man, I just learned about lemmy and a lot of decentralized platforms because I'm tired of my data being taken and bloated with ads. I'm assuming lemmy will be a safe place.
Each to to their own but I understand ur point. LN3 was made by Supermassive Games which is why most people disliked it as LN1 and LN2 were made by ThQNordic.
From what I was on YouTube, it does seem to be multiplayer because there are 2 YouTubers names 8-bit Ryan and Dawko who seem to be playing together. Thats the only evidence I am aware of honestly. The game came out a few days ago on steam and it was made the original creators of Little Nightmares 1 and 2. Little nightmares 3 is probably the one you are referring to which is made by Supermassive Games as it is not even cross platform or couch friendly and both users have to own a copy of the game. (which btw, best place to buy it is on steam to avoid needing to get ps plus/xbox gamepass)
Thank you for the correction
