Horu5: Welcome, welcome, welcome!
I was pretty surprised when I first stumbled across this site as well. When I learned about Customised Lemmings and the various clones and level editors, well, that was just the icing on the cake.
I've recently started constructing my own levels, hopefully to release the finished versions some time pretty soon. I'll try out your levels as soon as possible and get right back to you. 8)
Again: welcome! Good to see you.
