Mario Forever Season Collab - 霜降 (Frost's Descent) by the Ultra Team 

Is it he one presented by Games Mania TV (with a glitched platform in 4-3)? That's the only MF2015 I can remember having played.

@@wufeiling I mean, there was a folder called "MF2015" with reprints of foreign MF games hosted by you (under Reis nickname) on Pan Baidu cloud. The available screenshot shows that this folder had Mario Forever World Hardcore 3 by Night Fury, Mario Forever 2015 by Games Mania TV (the archive had a password) and some old versions of Mario Forever Roman Worlds and gameplay videos by Prokorsho Pal

I see. The new link is pan.baidu.com/s/12Avka6PJ7ssmb9bCkCGf3Q (access code: wayb)😀 And sorry for having given a wrong link in response to your request on marioforever.net. The correct one is Newlife2017's.@@Tomek839839

@@wufeiling Thank you so much for the new link! There are many works in this folder that have been deteted, lost or forgotten... (for example World H6, World Hardcore 3, "Mario Forever blue levels" and the Prokorsho Pal's video of roman world VIII)

Alternative link: pan.baidu.com/s/15AgSJmcKxfSbVeNKn9sXng (access code: 8ae8) The same content packed as RARs, in case the original folder is invalid.@@Tomek839839
