Hi Jammer64 (Welcome to the forums as well)
Just noticed your levels up on the mindless website, look good.
I like that there are more people creating level packs that's cool. I tend to like the occasional hero level such as Tim Foxy's levels such as (the swamp) level. (Fangorn Forest)
My dad was the first person to notice the solution when I played the onml crazy level 2, I was so excited when I got that game at christmas and stuck it into the Atari straight away.
I agree with what Akseli was saying in relation to levels having more than one solution which makes it more interesting, I can totally understand editing levels to stop backroutes as in some cases the backroute could make the level a lot easier but nevertheless lemmings is all about having different solutions I feel.
I might try your levels one time Jammer.
