Your EDM's Landon Fleury compared the song to Leusink's previous song "Skyforth", wring that the tack "sees Ephixa continuing down the house path in a similar way to his song 'Skyforth', but with a distinctly stronger groove and fresh vocal chops to top everything off". Fleury later noted Brehm's vocals as ones that "really soar, elevating the production to its maximum potential".

On December 13, 2017, Leusink collaborated with electronic music producer Bossfight to release "Subside" on Monstercat. Writing for Your EDM, Landon Fleury wrote about the song's influences from various electronic dance music genres including chiptune, synthwave, bass house, and trap, stating that the song "sees Ephixa turning back to the heavier-leaning sound his musical career was founded on, diving into electro at full power" and concluding his review by writing "Simply said, it’s a variety of different sounds and styles that somehow fit together perfectly in the end". The song was later featured on Monstercat Uncaged Vol. 4, the first compilation album released by Monstercat since their Uncaged and Instinct re-branding in January earlier in the year. The song appeared on Monstercat's Best of 2018 compilation album.

Writing for EDMTunes, James Brannigan noted the remix for its diversity and described it as "bearing a resemblance to Excision’s style". Matthew Meadow of Your EDM wrote that Luesink had transformed the original song into a "genre-hopping, deep and rumbling tune bound to blow your speakers", later stating that the synths used were "wonderfully bubbly and sinister at the same time, allowing for an extremely diverse and layered track, just the kind of thing I live for".

On June 30, 2014, a year after he released "Unraveled Reality" and almost two years after he released "The Anthem", Leusink independently released "Catfish". EDMTunes' James Brannigan noted the song for its minimalist trance progression, later writing that as soon as "the drop hits, Ephixa brings back the sound he used to win all of our hearts with as he did in his dubstep remix of 'Song of Storms'".

In November 2012, Leusink left Monstercat, continuing to release music independently. On November 16, he released "Fuck The System", a mashup of himself, Deadmau5, TVDS, and Showtek. The song was released to promote "Fuck the 9to5 jobs". On January 17, 2013, Leusink released "Unraveled Reality", which Steve Jacobs of EDM Sauce wrote that the track "offers a bit of a soothing feel along with some big drum sounds".

The remix was included in an extended play based on the original song, titled Sanctuary (The Remixes). When reviewing the extended play, a writer for DJ Mag commented on Leusink's remix, stating that he had gone for a "twitchy, spasmodic bit of dubstep-ery, which is ok, of the type". In the week of November 5, 2011, Leusink entered and peaked at number 11 on Billboard's Next Big Sound chart.

On April 10, 2010, Leusink released his second album, Zelda Step.

The album received mixed to positive reviews, with Jade Royal of Sputnikmusic giving the album a 3.5 out of 5 rating, stating "It's a thin line that Ephixa treads with 'Zelda Step', but one that ultimately pleases more than disdains". Elton Jones of Complex later placed Leusink's remix of "Lost Woods" as the best remix of a video game theme song, finalising his review of the song with "The Legend of Zelda Lost Woods theme mixed with dubstep sounds incredible."
