Sounds interesting. I remember wanting to make a song about blockland like, 5 years ago and was going to see if I could get a bunch of people singing along, but all that happened was I finished most of the song and then never got other people to voice things despite them saying they would. Sort of stuck in an unfinished limbo.
That being said the Fangel half of this account is up for singing. Don't have any recent voice samples used in song, but build-wise I have a bit more old-school "if I need to make a wall it doesn't matter how many lines are awkwardly about", but I've been occasionally booting up Blockland to work on a cruise ship (interior, exterior is terrible), so I can take pictures of that if needed.
