Fortunately this person waited until it was playable to reveal it, so you can download it now before it gets zapped. Many projects show off footage early to build buzz and get killed before dropping a download.

I mean... If it was online at some point, it's probably still out there for anyone that goes looking.

For example, Bloodborne PSX is still available at the Internet Archive; and Bloodborne Kart became Legally Distinct Nightmare Kart and is available on Steam.

If they didn't use the trademarked name, they'd probably avoid it all. Surely, there is a way to do this without forcing the trademark owner to issue cease and desists?

The amount of times this has happend with Nintendo leaves me mystified on why modders and devs don't bother to use anonymizing tools like Tor.
