So, in case anyone is wondering what's going on with Lemmings: Hall of Fame, I'm currently in the process of moving house, but more in a "piece-by-piece" manner that will likely take until March.
@kaywhyn, I haven't forgotten about your replays.
I'm just mainly spending my weekends setting up furniture at the moment.
I'll try to watch them all soon, but it will take a while until I have the time to edit the levels of the final two ranks accordingly.
Lemmings: Hall of Fame will still happen, but most likely later this year. I was shooting for a release at the beginning of the year; but then, I found the new apartment in autumn, and have only had access to it since once week before Christmas. March is when the living-room furniture arrives, so at that point it will be a lot more hospitable.
