Just a few levels.

[2112]

Right now, though, this thread only contains one level. That will change eventually - this, the first post, will contain links. Assuming any remake projects still exist and I submit any levels to any of them, numbers listed in this chart are not reflective of that. That information will be added later.

001.  Rhythm of Lem (this post)
002. (unknown)

Level no. 001.

Notes:
There's a small chunk of "steel" right by the wall near the beginning. When bombing that wall, this may not cause the wall to be destroyed right, and you may need to build. It was mostly put in place to force players to perform certain actions, that's all.
I probably need to center this. I'll have to check.

That's the only one at this time - expect more later, probably after I fine-tune the eight-entry level I attempted to devise...

I had a play and the level was challenging and fun .
