Editing Neptune

'''Neptune''' ('''IIINePtunEIII''' in-game) is a retired South Korean player and level creator. He was famous for his v2 levels and for making two famous difficult Demons, [[Necropolis]] and Deadly ClubStep. Ever since Neptune's v2 levels were first created, RobTop level remixes have been everywhere, from easy remakes to Extreme Demon remakes. During [[Update 1.9]], suspicion grew that Neptune was a hacker, and he soon quit in the middle of Update 1.9 for no apparent reason.

Neptune has created a series called 'v2'. These levels recreate the levels the titles represent (for example, if it is called Stereo Madness v2, the level will be a slightly more difficult version of Stereo Madness).

Even though Neptune made the series of 'v2 levels' famous (which even today is applied to remakes of levels), he was not the first to have the idea. In [[Update 1.1]], stars were given to the first level v2, called Sterio Madness v2 [''sic''], by an unregistered user named ferflappenDER (level ID 5639).

After that, popular Korean creator Rabb2t followed the trend, creating Dry Out v2, Can't Let Go v2, and Cycles v2; then, in [[Update 1.3]], Neptune finally created Stereo Madness v2 and continued with the next levels, popularizing the series. He also created Deadly ClubStep and Necropolis. Deadly ClubStep was considered impossible until LunarSimg beat it on mobile in [[Update 1.8]].

*In [[Update 2.0]], KaptainCPU made a fake account called JupiterGD. On that account, he said, 'Sorry for hack', and that Doomsday III, Deadlocked v2, and Geometrical Dominator v2 would come soon. However, Neptune (or possibly a hacker) posted on Neptune's account saying that JupiterGD is fake. JupiterGD then confessed and said the whole issue was a joke. It was an experiment to see how many likes a famous person would get compared to a non-famous person.

*[[Clutterfunk v2]] (Featured) - Neptune's remake of Clutterfunk, the second level in Remix Pack 4. Formerly a Medium Demon, it was downgraded to an Easy Demon because it was too easy for a Medium Demon.

*[[Electroman Adven v2]] (Featured) - Neptune's remake of Electroman Adventures, the third level in Demon Pack 7. Formerly a Medium Demon, it was downgraded to an Easy Demon because it was too easy for a Medium Demon.

*[[Theory of every v2]] (Featured) - Neptune's remake of Theory of Everything, the third level in Remix Pack 4.

*[[Xstep v2]] (Featured) - Neptune's first Easy Demon-rated level, a remake of xStep, the first level in Remix Pack 4.

;Cancelled/deleted levels

*Abaddon - A level that they said was coming soon in the comments of their first RayCrisis video, but it never came. Only one screenshot is known to exist.

*cycles v2 - The original ([[Update 1.2|1.2]]) version of Cycles v2 R, formerly rated Insane 8*. It was derated because it became impossible in a later update, then was deleted.

*NightDay - Formerly rated Normal 3*. It was derated and deleted for an unknown reason. No known footage exists.

*[[Red World]] - An Extreme Demon collaboration with [[saRy]]. It was the first level to use blue orbs to create gameplay mechanics later refined into the swing game-mode in [[Update 2.2]]. It is also an Extreme Demon with the lowest ID.

*Neptune has made the first 'Spike jump' in-game. It is usually a [[Update 1.7|1.7]]-coloured block with blending and black, making it a truly invisible ramp/block. It was later used in several hard levels. (This was mostly using invisible blocks before Alpha Trigger was implemented.)

*Neptune's v2 remake of Cycles is labelled 'Cycles v2 R,' while the rest of his v2 remakes end with just 'v2'. He replied to a question about the purpose of the R in his YouTube video and the level description in Geometry Dash. The 'R' at the end stands for 'Remake', most likely because it is the second version of the original deleted Cycles v2.

**Although someone may have hacked into Neptune's account and said that, it would mean his actual last message was 'I'm not used hack :('.
