AFAIK, there shouldn't be any problems regarding physics on any of the levels. Of course, as usual due to unusual quirks and behaviors (eg, climbers being able to climb past thin enough ceilings when they shouldn't) that you found from converting Reunion and Pimolems, there might be some surprises here too. It's been a really long time since I played the pack, so I don't remember too many of the levels. From what I remember, it's an excellent pack. Also, mobius is not maintaining this pack anymore for the Lemmini version, at least in terms of backroute fixes, and so keep in mind that any solution you find for the levels will be fine and that the Youtube solution will likely be one of many, and so just solve the levels in any way you want. Thus, the conversion will probably be really fast. Besides, it's much more fun solving levels on your own before viewing replays/solutions. It's how you get better at level solving anyway. Not to mention the difficulty of the pack is pretty much at about where Sublems is, so should be the perfect difficulty for you, and it's likely I won't even need to send any replays for any of the levels to you. However, I will help out to provide them wherever you're missing them when I get around to those other packs, of course. There probably will be no need to make notes for any of the levels for each difficulty, unless you want to, of course. I do know that it helps to keep you organized, so you should do whatever will help you remember important things. I do say that I get a kick out of reading your notes about each level, but you're not under any obligation to do so just because I like reading your input.
