On 25 November 2016, the game successfully completed a
Kickstarter campaign raising funds through 1,592 backers. The campaign raised just over €32,000, quadruple the intended goal of €8,000. The additional funding allowed for more content such as endings, items, and characters. A roster of notable voice actors was assembled to portray the cast, including
Arin Hanson,
Dan Avidan, Nathan Sharp,
Cristina Valenzuela,
Sarah Anne Williams,
Christine Marie Cabanos, Danielle McRae,
Erika Ishii and others. On 14 February 2018, the developers announced the game's release via a teaser trailer, and the game was released on 27 April 2018 on
Steam for Windows, Mac OS, and Linux. The
Second Term expansion
DLC, which was a stretch goal of the Kickstarter campaign, was released on 14 February 2019, adding additional voice work from
Felicia Day,
Casey Mongillo,
Jacksepticeye,
Ross O'Donovan, and
Anna Brisbin. The campaign proved successful and raised over €535,000 from almost 9,000 backers within a month, surpassing their goal of €32,000. As development progressed and the game's scope grew beyond the team's expectations, the decision was made to release the Summer Camp portion of Holiday Season as its own game title,
Monster Prom 2: Monster Camp, which was released on October 23, 2020. Damien and Calculester reprise their roles as romanceable characters, and three NPCs from the original game - Aaravi Mishra, a monster-human hybrid and monster slayer; Dahlia Aquino, a female demon; and Joy Johnson-Johjima, a
witch - as well as a brand new character, Milo Belladonna, a
death reaper, also appear as romanceable options. Initially, the plan was to release
Winter Retreat and
Roadtrip under the title
Monster Memories, along with an additional DLC game titled
Monster Prom: Not Another Isekai!, which had been achieved with the extra funding on Kickstarter. However, like
Monster Camp, these games were separated into their own individual titles. On April 28, 2022, Beautiful Glitch released a reveal trailer for
Roadtrip, now titled
Monster Prom 3: Monster Roadtrip, which was later released on October 21, 2022. Additionally, Beautiful Glitch was able to fund a spin-off game through the sequel's Kickstarter titled
Monster Prom: REVERSE, in which the playable characters from the first game can be romanced. On May 3rd 2024,
Monster Prom 4: Monster Con was announced. In this iteration players have the chance to romance series regulars Liam de Lioncourt and Zoe, as well as 4 new characters - Nico Sharp, a
mimic; April First, a clown; Doug Campbell, a slime; and Omen, an "unknown monster type." As the name implies,
Monster Prom 4: Monster Con takes place at a comic convention. New locations include the Main Stage, The Lobby, Community Zone, Merch Hall, and Hotels and Outdoors. The game was released on April 24, 2025. ==Reception==
