The game was developed by
Squanch Games, which was founded by
Rick and Mortys co-creator
Justin Roiland; it was the studio's third game.
Trover was mainly designed to be a comedy game, with Tanya Watson, one of Squanch Games' co-founders, adding that "if people don't laugh when we intend for them to laugh, then we know that something isn't working". While Roiland initially believed that the game would be well-received as long as it had good gameplay, as development progressed, he felt that the game "needed to be just as tight and funny as a TV production" because some of the in-game jokes were not working effectively. While Roiland and his team had laid down the foundation of the story, the voice actors were given a lot of room to improvise. Roiland himself also recorded more than 20 hours of lines for the game. The team also observed playtesters' interactions with the game's world, and added additional lines in order to react to these possible actions. However, nearly 40% of the recorded lines were not used in the final game. Roiland envisioned the title as a virtual reality game after being impressed by VR technology in 2015. Two important goals for the team were to instill a sense of exploration to the game and ensure that players would not get
motion sickness while playing. The game is also playable without using a VR headset as the team feared that it would limit the game's audience. According to Roiland, "everything is just as funny and amazing" even when it is played without a VR headset. It was released for
PlayStation 4 and
PlayStation VR on May 31, 2019. The
PC version was released on June 4, 2019.
Gearbox Publishing assumed publishing duties for the boxed version. Squanch Games released a trailer featuring
Rick Sanchez and
Morty Smith from
Rick and Morty in June 2019. The developer supported the game with free
downloadable content with the release of "Important Cosmic Jobs" and "Jopo Mode" following the game's launch. In November 2019, Squanch Games announced that the game and its DLC would be launching on
Nintendo Switch and
Xbox One on November 28 and December 3 respectively. An Oculus Quest version was released on June 18, 2020. ==Reception==
