Great level for LBP1. Imagine the amount of pistons and player sensors required to make the level work! That's LBP dedication or insanity
There was a brilliant LBP2 level called "+2000 emitters + Stormy night Edition" by yenahc 1962 which also made itself as you went along but unfortunately I get a "404 page can't be found message) to find a link to it.
The gas in LBP1 doesn't transfer well at all into LBP3 . Often the colour which you had carefully chose to fit in with the theme just turns out black in LBP3.
