Editing Firework (section)

===Development===
On 7 April 2019, Vernam, the leader of Cherry Team at the time, published a video on YouTube titled 'Firework is literally impossible in current state (Bad noclip and Broken sync)',<ref>https://www.youtube.com/watch?v=X8txbdNUcQ0</ref> showing the first ever preview of Firework. Vernam mentioned that Cherry Team members would decorate the level as the team's newest project. Vernam initially intended for Firework to be decorated in blue, orange, and green. However, implementing these colours was too complex, so Vernam went for a simple black-and-white scheme. A few parts were completed two months after the first preview was posted: Lilium's first part, Konsi's part,<ref>https://www.youtube.com/watch?v=Dm9MGLffEVE</ref> Grayrain's part,<ref>https://www.youtube.com/watch?v=KjkZ-k2l5bU</ref> and Desumari's two parts. Because the level's production was moving swiftly, Dolphy, the verifier at the time, published the first Firework preview to his channel, showcasing each of the previously listed parts.<ref>https://www.youtube.com/watch?v=F8aoM-71Qy8</ref>

Shortly after the preview, several other creators uploaded their parts, including Deron,<ref>https://www.youtube.com/watch?v=Bzh1IiofTUU</ref> Buragoz's two parts,<ref>https://www.youtube.com/watch?v=ZuRguCB_ah4</ref><ref>https://www.youtube.com/watch?v=mP1e5LPr8pQ</ref> Itami (who replaced Grayrain's part),<ref>https://www.youtube.com/watch?v=nM-w39jVh0o</ref> RealVet (who replaced Desumari's second part),<ref>https://www.youtube.com/watch?v=NB5KLhM1hB4</ref> and OfficialFreck.<ref>https://www.youtube.com/watch?v=dgGH-nj8xcg</ref> OfficialFreck, however, later got replaced by Crouley,<ref>https://www.youtube.com/watch?v=Vb1sETilPbQ</ref> as well as Deron by 00Zero. Some of the decorators were working behind the scenes and not releasing footage of their sections, but these parts were later exposed in a montage released by f3lixsram on Christmas 2019.<ref>https://www.youtube.com/watch?v=SFcq8XWspD0</ref>

A little more work was done behind the scenes before the level was properly merged and polished. Dolphy then posted a full-level showcase on New Year's Day 2020.<ref>https://www.youtube.com/watch?v=-aW6xOpWzJo</ref>
