Editing GRIEF (section)

===Verification===
Doggie began streaming GRIEF on 1 May 2024. For his first achievement on the level, he tried to complete a 65-100% run, which he eventually accomplished on 27 May 2024 on stream #16, comparing it to beating a Top 20 level like [[Edge of Destiny]].

Doggie first reached the drop on 30 May with 27%. In later streams, he mostly played runs, though he occasionally started from 0% and made some progress. On 14 July, he achieved 41%, which remained his best for nearly two months. He completed a 56-100% run on 17 July and a 49-100% run on 29 July. He finally broke his 41% record on 19 August with 47%. Two days later, he got 49%. He finally reached MercuryDT's part on 13 September with a 52% best, followed by a 54% best three days later. He reached the level's extension on 25 September, achieving 56%. One day later, off-stream, he reached the second drop, achieving 68%.

Doggie's consistency declined steadily in October and continued into early November, prompting a short break. After returning, he quickly reached 80% on 24 November. He then took another break in December due to his school commitments. Progress remained slow until late January, when he started reaching the second drop more often. By February, he was reaching the second drop in nearly every stream. He achieved a 25-100% run on 26 February on a slightly easier version of GRIEF, which was his best run to 100%. Progress eventually slowed, with Doggie not reaching the second drop at all for over three months, starting in mid-July. Finally, in November 2025, Doggie would achieve a new best of 83%, sparking new confidence and consistency in the verification after that point.<ref>https://www.youtube.com/watch?v=mp8TSHLoW8Q</ref>

In 2026, Doggie streamed the GRIEF verification almost every day of February 2026 (26 days, taking two breaks to rest his hand)<ref>https://www.youtube.com/watch?v=I-v769GzrjQ&t=196s</ref> and reached greafer (66%+) on every stream in March. He has achieved several notable attempts since his return on 21 January 2026, including 73% three times, 78%, 79% twice, 80%, 81% twice, 35-97% twice, 25-92%, 25-95%, and 25-100% four times.<ref>https://docs.google.com/spreadsheets/d/1ldsEF0yNXeTS1r5rape9wjTLor6KWyeJvZk9-_HdFrE</ref> From this observation, this month's session has been his most consistent one for reaching GrenadeofTacos's part so far.

Doggie continued to stream periodically. On 28 April 2026, Doggie created a slightly nerfed version of GRIEF, moving obstacles by only a micro-step to help him improve on the level and hopefully perform better on the real version.<ref>https://www.youtube.com/watch?v=ffMCLmnhKC4</ref> On 7 May 2026, [[Zoink]] decided to join the verification race for [[Heliopolis]], leading to a competitive Top 1 verification race. On the same day, Doggie reached 84% after six months from his previous record,<ref>https://www.youtube.com/watch?v=VLqlssP1Dxw</ref> which, ironically, he mentioned earlier in the stream he did not want to fail there.<ref>https://www.youtube.com/watch?v=JBgbzet6-yY&t=896s</ref>

About a month later, on 14 June 2026, Doggie finally broke the barrier of GrenadeofTacos's part, almost fluking the end, and failed at 97% on his 361st stream.<ref>https://www.youtube.com/watch?v=Emd2tWP2FkI</ref> On 21 September, Doggie failed at 97% again on his 390th stream, followed by another ending run of 91% during the same stream.<ref>https://www.youtube.com/watch?v=_nv9UsomBi0</ref><ref>https://www.youtube.com/watch?v=ro__P8vGP6k&t=9204s</ref>

On 5 October 2026, two years and five months after the first stream, Doggie finally verified GRIEF during stream #396 after 436,879 attempts.<ref name="Verification" /> The Geometry Dash community's reaction caused the game's servers to crash, along with other related websites, due to a massive traffic surge.
