Hey, Chronamut, welcome to the Forums!
Not a bad remix. I do recognise all the songs and noticed one of them plays twice. It sounds relaxing for the most part, then the drama really cranks up at 9:10. I'm wondering, what music tool did you use to make this remix?
IchoTolot has released a Lemmings Pack called
Lemmings Reunion. If you download this along with NeoLemmix, you may find some more Lemmings remixes. Not sure what the exact files are, as there are about 40 of them and that they're not properly named, but they are there.
As for me, 4 years ago I've remixed the Oh No More Lemmings songs in a MIDI format. The thread and the music can be found
here.
