Adult Swim is no longer able to continue as publisher for this game and the developer is not available to take over as publisher at this time. As a result, Super House of Dead Ninjas will be shut down on July 15th, 2024. Thanks for playing. Adult Swim Games
Nobody is available to act as publisher following Adult Swim Games shutting down. That means it won’t be available to buy soon.
Just a guess but I imagine the economic feasibility of purchasing those publishing rights is the main hang up.
Publisher could be cool or they could squat on an IP for decades doing nothing. Who knows.
