I think it's harder to make good levels like this due to the simple fact you can't rely on decorations, only on gameplay, some effects and overall feeling that the level conveys visually through gameplay flow. Since that's a building skill set that fewer people have, it takes more to improve this relatively new trend, and thus making it harder to create
By far my favourite LeaF's song Its simply amazing, and the level fits everything! Yes, the intro is a little scary, but its exactly what the song is based off. I love it!
This level would be extremely difficult to decorate and still be playable but if someone pulled it off this would be number 1 the effects them selves are amazing it doesn’t even need deco
Just to say Leaf also made the song 'Peaceful' and 'Aleph 0' and this of course :) Damn Leaf songs are gonna be the new popular song now can't wait to see a spam of songs from leaf xD
