The "Gollum" devs, Daedelic, have been around a long time. They were mostly known for classic 2D adventure games, the best known among them were probably the "Deponia" series.

They wanted to go big with "Gollum" and failed even more spectacularly than most people realize: They already ran out of money in 2021 and had to sell themselves to a bigger company who brought in additional funds in order to finish the game. And even the money Daedelic got through that deal was limited, so they had to push out the game no matter what.
