no assignment field sounds like it has a lot of potential for backroute fixing, possibly.
This is one of the reasons I don't like the idea of this object, to be honest. A perfectly backroute-proof level, to my mind, is just as arbitrary as a trivial "Just (Skill)" level; it might as well
be a tutorial level. The first 7 levels of
Lemmings are about as backroute-proof as that game gets!
In other words, it's not giving the player any options other than to "paint by the numbers" and follow the
exact intentions of the level designer. Levels like these can, on occasion, be quite fun if they happen to reveal a certain trick or if they have one of those "aha!" moments when you realise how to traverse a particular obstacle, but too many of them can just start to feel like you're following instructions rather than playing a game.
I realise that this is more of a mini-rant about backroute fixing than a comment on the object itself, so I'll just add to this that a no-assignment field is likely to be simply treated as another trap to be avoided, albeit one that doesn't kill the lemming.
Sorry for jumping on your comment there, mobius! I think it's just something I felt needed to be said
