A Beast of a level, MENACING, What an AWESOME level and A BeastII of a level, if only for the graphics.

Shaded are the better ones:

We are now at LEMCON ONE
Easy when you know how

And I'll select the good ones from ONML when I have a list of them, but for now I like Synchronised Lemming, PoP YoR ToP and PoP TiL YoU dRoP.

As in, can you list them all without checking an online walkthrough or anything; I can do this with Lemmings but not with ONML.
Or, I can do it with most of Lemmings. For some reason I forget the names of some fun levels.

Mayhem 25: Have a Nice Day!

Good: the scenery at the sides

Bad: not much more difficult than the Tricky version.

cool

I don't know any of these. Can you impart your knowledge?
How is there an "obvious" one in Family Tree?

I have passed all the levels at one time or another, afaik. Some (like Triple Trouble and Save Me) I am almost never able to complete, and it is truly a cause for celebration when I do.
Others (like Rendezvous at the Mountain) I've not had much of a chance to try properly, and have completed on the mac version. On the playstation version I got this far and then couldn't pass it for some reason.
At least one level on ONML has a bug in the mac version whereby a wall that's apparently flat and climbable on the DOS version is bumpy and unclimbable. I did eventually get past it, though, when I used builders instead, but this was very difficult to pull off.
Also in ONML I had problems with Havoc 4, where I was having great difficulty timing the mining to the left, at least certainly on the playstation (I did eventually get it, but I have no idea how). On the mac it was easier because you can hold alt to not select the active basher.

Funny, the solution to Just A Minute has always seemed obvious to me; the only difficlty is the time limit.


Mayhem 17: Stepping Stones

Good: Nice idea, quite challenging
Bad: Annoying if you miss the Stones, and because you have to "remove" the blocker by building over him, which is difficult to time accurately.
