I wanted to make a ctm that stood out from all the others, so I came up with an idea to make it a one block lane. I didn't know if people would like it or not so i made a kind of demo version with only 2 wools.
First of all, this is a very odd idea. I'm sure no else would ever have considered it. But still, kudos for doing something unique.
I examined it in MCEdit, and the implications of having things one wide are quite obvious. Namely, everything is given in a chest, and the landscape is always the same - bedrock walls. There is no opportunity for players to harvest materials or anything, because there's no space. There's also not many traps, because the limited space makes them easy to spot.
I'd recommended at least a three-block wide, if not five or more. It's difficult to do such a thing, but
"At least we tried."
P.S. That slime spawner won't work. It needs to be in layers 0-16 and in a chunk that can spawn slimes.
P.P.S. If it sounds like I'm bad-mouthing, I'm sorry.
