Print ondemand can be ordered for less than $5 per zine in Lulu, since 2022 or so. I guess Zach doesn’t make a cut from it since this $5 probably barely covers the cost of print and Lulu fee :(

Same, I played SpaceChem in high school and it captivated me. A lot of my solutions were unoptimized sync monstrosities and the boss battles filtered me pretty hard, but man it was satisfying to figure out a solution and just watch it create the molecules. The music was amazing too, it was on my study playlist all through university.
