Leffen was unable to enter The Big House 5, Smash Summit, GENESIS 3, Battle of the Five Gods, and Smash Summit 2 due to international visa issues. Furthermore, he was denied a worker's visa from the United States, primarily for reasons that question Melee's legitimacy as a sport. The video showing the rejection letter has started a movement to reverse the decision. Eventually, Leffen came to be temporarily allowed into the USA up until and throughout July 2016, letting him attend EVO 2016.

Other Smash games
Leffen is one of the top Melee Fox players in the world. He has solid fundamentals in all aspects of the game, using a methodical and efficient approach, making him a very well-rounded player. Leffen has a great neutral game, as he rarely overextends or overreaches in games, and has excellent movement. He is also known for his heavy combo game, especially on fast fallers, and has one of the most potent Foxes in the Fox ditto and the Falco matchup. Leffen is also very consistent, and rarely drops tech skill inputs. While Leffen is well-rounded, he undoubtedly focuses on the mental game and adaptation more than technical play. Leffen has once stated in an interview that he believes many high-level players are held back by "flowchart" behavior that he is able to exploit. This is clearly exemplified by his ability to clutch out sets; Leffen has made many match-winning reversals from 0-2 deficits. While he may not be as technical as other players, he is very adept at using all of the tools available to him in any given situation.
However, Leffen is known to have slight trouble against punish-heavy players, although this has been dramatically improved over time. Despite his strong fundamentals, he struggles if his opponent can consistently put him in a punish, as his ability to negate the effectiveness of opponents' punish games is not as strong as that of players such as Mango and Hungrybox. Because of this, he has dropped sets to punish-heavy players, such as Silent Wolf, Westballz, and Ice, and for a long time, was unable to defeat Mew2King. Leffen is also noted to be fairly poor at the Samus matchup, having a 2-1 record with HugS and a 1-2 record with Duck, both of whom are considered far below his skill level. He has also lost twice to Plup in solo Samus sets.
Despite being considered one of the best professional smashers in Melee, Leffen has led a controversial career as a smasher, due to his previously rude conduct during and outside of tournaments. Several players, most of which were new smashers to the scene, accused him of:
After noticing his poor behavior, Swedish tournament organizers and other Melee professionals of his caliber gave him repeated warnings concerning his attitude. In August 2012, Leffen was eventually threatened with a ban from tournaments if he did not improve his attitude, but he did not take the claim seriously. This led to further lengthy online discussions among the European Smash community that culminated in his national ban from Swedish tournaments, effective February 9th, 2013.
The discussion group announcing his ban compiled a significant amount of evidence of his poor behavior into a downloadable archive, and demanded that Leffen create a lengthy apology about all of his wrongdoings and how he would change his behavior in the future, should he return to the community. On March 21st, 2013, Leffen made his public statement asking for forgiveness; despite this, he was not immediately unbanned, and ended up missing almost one year's worth of local tournaments. On January 24th, 2014, it was announced by Armada that the Swedish ban on Leffen was no longer in place . However, Leffen still remains a relatively controversial figure in the community, especially on social media such as Twitter and Facebook due to his blunt comments.
At European tournament Heir II the Throne, Leffen was banned from commentary on all future European Smash Circuit events for saying that it wasn't a 'serious' tournament and players were playing their secondaries and not trying.
