YunHaSeu14

YunHaSeu14 (also shortened to YunHaSeu, 윤하스) is a South Korean mobile player and level creator. She was around during the 1.0 era, as she released her first level, Blue Legend, rated Hard 4*. Most of her levels range from Normal 3* to Harder 7* difficulty. She has released a few Demons since her Medium Demon level 'Championship' back in Update 1.7. Still, only one of the Demon-difficulty levels released after the earlier mentioned got rated—a 2.1 Easy Demon named Mischief Maker.

YunHaSeu14 is #2 on the Creators Leaderboard, below Split72.

History

YunHaSeu14 started playing Geometry Dash from v1.0, during which she released Blue Legend and Rainbow Sky, the latter of which would be her first featured level. Later, in 2014, her rank on the Creator Leaderboard was #36. Eventually, she reached her second-highest position on the leaderboard at #6, with 24 Creator Points.

During Update 1.9, her Creator Leaderboard position lowered to #33. Then, during Update 2.0 from 2015, she was ranked #49 on the Global Leaderboard. In 2016, she was ranked #46.

From 2017 to the present, she created levels using old-style, glow, and modern designs for most of them and parts in collaborations. As of 23 November 2020, she had climbed the leaderboard again and was now ranked in the Top 15 on the Creator Leaderboards.

On the first day of 2021, she released the first rated level, ZOZI, a collaboration with Partition. However, on 17 January 2021, she checked the Creator Leaderboard and realized she was #11, so she still had a chance to make it into the Top 10. On 5 February 2021, YunHaSeu14 reached the Top 10.

On 11 March 2021, she explained that her unrated levels 'TEN', 'Minikin', and 'Yarr' are of Demon difficulty. She released Demon levels since Update 1.7, although they were never rated.

On 11 June 2021, she reached 2,000 subscribers on YouTube.

On 30 September 2021, her five-year-old phone suddenly broke, and she bought a new one. About the incident, she stated:

“

Hello, its Yun.

Many people know that I'm mobile user. Today, my phone (which I have been using for 5 years) suddenly broke down. The screen is not visible and the touch isn't working well. As a result, it has become difficult to play and create GD levels now. First of all I'm in a situation whise I have to fix a broken phone or buy a new one. If I fix my new phone I can keep GD save, or If I buy a new phone, GD save will go back to 2 month ago. So the levels about that I'm creating and Stars about that I'm saving will disappear. Most likely I'll just buy a new phone. If it's resolved, I'll let you know later.

Thank you.

~ YunHaSeu14

On 2 October 2021, she bought a new phone with more RAM and less lag.

On 8 October 2021, she reached the Top 5 on the Creator Leaderboard, surpassing Experience D. On 26 October 2021, she reached 200 Creator Points. On 17 February 2022, she reached the Top 3 on the Creator Leaderboard, surpassing ZenthicAlpha and becoming the highest-ranked Korean creator on the leaderboard. On 15 March 2022, she passed Serponge for the #2 spot on the Creator Leaderboard.

On 2 December 2022, she finally dethroned Viprin's #1 spot on the Creator Leaderboard after his nearly eight-year reign as the Top 1 creator. On 15 March 2023, she reached 300 creator points, becoming the first person to do so. On 29 January 2025, she was finally passed by Split72 after two years, pushed to #2 on the Creator Leaderboard.
