Spritekit Pro exists because I spent a year reading this forum without posting, then got tired of my own pipeline breaking. 2D game asset pipeline: drag a folder, get atlases, previews, and exports for the three engines people actually use. 2,100 euros MRR, Kyoto, one customer email that just says "it worked" printed above my desk.
Lurking year verdict: reading teaches the vocabulary, posting teaches the gaps. My first post got three corrections and all three were right. Post earlier than I did.
Question for shippers: what is your "it worked" metric? Mine is support tickets that say nothing except thanks.
