Don't get me wrong, I made some splat-hatch levels myself, but then it's precisely as you guys said: Catching the crowd is already part of the solution. Poor Wee Creatures is the only level in original Lemmings where I agree this is useful; Bitter Lemming / With a twist of Lemming, please and Steel works, meanwhile, merely delay the actual puzzle with this start. As you will see in the thread Proxima linked to, namida indeed agreed with me that With a twist of Lemming, please is the worst offender in this regard.
Meaning, simply giving the player a bunch of Builders and Floaters is precisely NOT how it should be done
- at least not in NeoLemmix, where you have much more elegant and less repetitive ways (e.g. send a Glider towards a wall and bomb him to make a dent, then send a second Glider / clone the first one twice to get another one into this direction, then have him build a single staircase or platform from there that serves as a splatform).
And I've seen similarly "useless" splat hatches on custom levels. There was one particular brick level at the end of the first rank of DoveLems ("Cisterns, Chains and Bricks"), where you just have to build a random staircase under the hatch to prevent everyone from splatting at the start. The actual puzzle however is getting a Climber up a wall on the left or right and then navigating downward cleverly through a maze. This is the actual puzzle part, and it has nothing to do with the splat hatch at the beginning. It's just unnecessary delay of a solution to an otherwise very interesting level.
