SuperMarioGlitchy4's channel seemed to be struggling at the beginning of 2015, given the fact that the first blooper of the year involved him running out of ideas. However, SMG4 later assured his fans that he did not in fact have an idea block, followed by the release of a new blooper and Retarded64. These new videos notably reintroduced the Super Mario 256 font that had randomly disappeared during the end of 2014 though not in 2013 style (having a very thin outline with a different-colored fill inside the text). The five first bloopers of the year were uploaded on Monday instead of Sunday (although it was still Sunday evening in the West (America) when SMG4 published the video Castle Royale).
In 2015 (just like in 2014), YouTubers still appear very rarely. They only made cameos from some first bloopers and then almost disappeared all over. Even SMG4's newest bloopers are often not getting him inside them as a main characters or not even a cameo. SMG4's videos also have better quality this year, probably he switched to Bandicam because the black lines were removed. Also, Steve doesn't make as much appearances this year. MM54321 was also limited to only one appearance in 2015.
2015 was the year with the least number of SMG4 videos, as there were only 16 bloopers uploaded on the 11st of May, while there were 21 videos at the same date on the previous year (22 if the trailer video "WELCOME TO SMG4'S MAGICAL LAND OF RETARDEDNESS" can be counted), because there were several weeks within which SMG4 couldn't release any videos mostly due to school.
