YerkDiff: The Developer Behind Scarlet Skips

Scarlet Skips was made under the handle YerkDiff. Steam credits Yerk Games as the developer and publisher of the one-button jump-rope roguelike, the listing's copyright line reads © 2026 YerkDiff, and the five accounts that promote the game all run on one handle — YerkDiff, displayed as Yerk. Those details are the entire official paper trail. No official channel names the person behind the handle, says how many people built the game, or states whether Scarlet Skips was a solo project. This page collects what the YerkDiff accounts and the Steam listing actually document, and it flags every creator question that official sources leave open. Counts below are the figures those accounts carried when they were checked on September 30, 2026; social numbers move constantly.

Who is YerkDiff?

YerkDiff is the creator identity behind Scarlet Skips: one handle across five platforms, each account pointing back at the game's Steam page. The display name on those accounts is Yerk rather than the full handle, which is why the same creator turns up as "Yerk" in community posts and as "YerkDiff" in links, bios and the Steam copyright line.

Platform	Account	What the account states (checked 2026-09-30)
X	x.com/YerkDiff	Bio points straight at the Scarlet Skips Steam page; 6,506 posts at the time of checking
YouTube	youtube.com/@YerkDiff	115K subscribers, 68 videos, bio "I like to make cool, cute and funny stuff :)"; the channel links to the Steam page
Instagram	instagram.com/yerkdiff	51K followers, bio "I'm making a game called Scarlet Skips! Wishlist on Steam"
Bluesky	yerkdiff.bsky.social	"Hey look at me! It's that Yerk fella! Wishlist Scarlet Skips on Steam"
Patreon	patreon.com/YerkDiff	"creating Cool, Cute, and Funny Stuff"

Two things follow from that list. First, the accounts read as creator-run rather than company-run: the bios speak in the first person and describe a person making a game, not a studio publishing a catalogue. Second, the platforms agree on the same handle everywhere — X, YouTube, Instagram, Bluesky and Patreon all resolve to "yerkdiff" — so the identity can be checked by matching handles rather than by trusting any single profile.

Note on platform lists: the SteamDB social block captured for our Steam page also listed a TikTok account on the same handle. The material checked for this page documents the five platforms above, so the count depends on which source, and which date, is quoted.

The accounts are also where the few public statements about development originate. One X post compares the time spent on Scarlet Skips to the time spent making "the Mario Maker" — a comparison, not a schedule. Unconfirmed: what that sentence refers to in full, and any actual development duration, since the snapshot does not include the surrounding posts and no other channel puts a number on the development period.

The developer behind Scarlet Skips

The commercial record sits on Steam, and it is unusually thin for a released game — which is the point.

App ID: 4513480 on the Steam store.
Developer and publisher: both fields read Yerk Games.
Released: September 3, 2026, for Windows PC.
Price: $4.99 USD list price at launch.
Genre: Action, one-button jump-rope roguelike.
Interface language: English only.
Steam Deck: Verified.
Achievements: one.

The copyright line under the listing reads © 2026 YerkDiff, and that is the single official detail connecting the studio credit to the handle this page is about. It is the same link described on our overview page: Steam names Yerk Games, the copyright names YerkDiff, and neither names a human being behind them.

Unconfirmed: the relationship between "Yerk Games" and the YerkDiff accounts beyond that copyright line, and any list of people credited on the game. Steam's credit fields are the only official authorship information available.

Because the store page and the copyright line are the only authorship sources, this page works best as an index for creator questions rather than as a biography. Everything else about the release — price table, regional pricing, review fields, system requirements — belongs to the Steam page, which carries its figures with their own retrieval date.

One more documented thread runs from the handle to the artwork: fan-run pages describe Scarlet, the red-haired jumper, as a pre-existing YerkDiff original character rather than one created for this release. No official source has confirmed where Scarlet came from, and the characters page keeps that question open rather than resolved.

Community connections

Two third-party threads attach to YerkDiff specifically, and both need the same caveat: neither is an official statement.

The Dani playtest thread. A post on r/DaniDev is titled "Dani helped playtest YerkDiff's new game Scarlet Skips" (reddit.com/r/DaniDev/comments/1w9rqpe). Dani is the developer behind Karlson, and a playtest cameo from another independent creator is an appealing story — which is exactly why it needs marking. The claim is community-circulated; no official channel from either creator, and no part of the Steam listing, confirms that a playtest took place.

Unconfirmed: that Dani played or playtested Scarlet Skips. The claim comes from a player-community post in a subreddit dedicated to Dani, and it has not been confirmed by YerkDiff, by Dani, or by any official source. Treat it as a rumour that may well be true, not as a documented collaboration.

The TCRF entry. The Cutting Room Floor, the wiki that documents unused and prototype content in released games, hosts a page at tcrf.net/Scarlet_Skips. The entry exists; that much is verifiable. Its full contents were not retrievable when this page was checked, because the site served a challenge page instead of the article, so nothing from the entry's body is reproduced here.

Unconfirmed: the specifics the TCRF entry documents, including material apparently concerning a hidden jump easter egg for Scarlet in a prototype build. Only the page's existence is confirmed here, not its claims.

Community discussion of Scarlet Skips more broadly is covered on our community and Reddit status page, which separates the channels that are actually verified from the ones that are not. The pattern is the same one that applies here: player interest is real, official detail is scarce.

What remains unconfirmed

The YerkDiff handle is easy to verify; the person behind it is not. Every question below sits in the same place — documented channels, no official answer.

Real identity. No official source gives a personal name, location or biography for the creator behind YerkDiff. The handle and the display name "Yerk" are the documented parts.
Solo developer or team. No official statement says whether Scarlet Skips was built by one person or by several. The one-person presentation of the accounts — first-person bios, a personal Patreon, a single credited copyright name — is suggestive, but it is not a statement.
Team size. No headcount appears anywhere official. Steam's developer field is a name, not a number.
Development duration. The only public remark is the "Mario Maker" comparison on X. No official figure for months or years of development exists.
Other projects and credentials. No official source lists earlier releases, prior studios or contract work under this handle.
Future plans. Nothing published states what the creator intends to build next.

Unconfirmed: the creator's identity, the number of people who worked on Scarlet Skips, whether the game was a solo project, and any exact development duration. No official channel has published these details, and none of them should be inferred from account styling, follower counts or platform type.

That is a deliberate stopping point rather than a gap to fill with guesses. Two rules keep creator research clean here: verify the handle — X, YouTube, Instagram, Bluesky and Patreon all use "yerkdiff", so a mismatched handle is not the same account — and check the date on anything you read, because the game shipped in September 2026 and every count on this page is a snapshot.

FAQ

Who is YerkDiff? The creator identity behind Scarlet Skips — one handle across X, YouTube, Instagram, Bluesky and Patreon. The bios describe the person making the game, and the handle matches the copyright line on the Steam listing.

Did Dani playtest Scarlet Skips? A post on r/DaniDev says so, and no official source confirms it. Under the verification standard this site applies, that makes it a community rumour.

How long did Scarlet Skips take to make? No figure is published. The only public comment is an X post comparing the development time to making "the Mario Maker", which is a comparison rather than a duration.

Where can I check this myself? Start with the Scarlet Skips Steam listing for the credit and copyright lines, then the five accounts listed above. The overview page and the Steam page repeat the same facts with their own data dates.
