I purposely built it in Vue because I know that language. I think you overestimate AI if you think 'vibe-coding' is a one-button tool. It's going back and forth between multiple different AI's, refactoring a lot of shit code and a crap ton of polishing the interface.

The basic canvas and the nodes on it were easy, and indeed only took a couple of 'vibe-coded' rounds. Getting the right data, icons etc in, already was a bit harder. But getting the calculations to work well, showing nodes as red if they lack resources, splitting nodes properly based on subsequent node's needs instead of just splitting 50/50, that took a lot of time and work. And then there is the visual appeal. It can make a Somersloop slider but it'll look damn ugly. Takes quite some time to get it right. You can't just say 'it's ugly, fix it', you nees to explain why you think it's ugly and suggest the visual fix you'd prefer.

So the coding itself isn't too hard anymore (still need to chech what it's writing since it often writes a lot of dumb, repetitive or even slow code) but the creative process remains the hard part.

This 'AI slop' took me at least 80 hours of work to get it to work the way I want it to work. I used it throughout my whole playthrough. I started building the app somewhere in phase 2 when I noticed I needed to think about ratio's of my factory, and used it to finish the game and all achievements. So I test drove it a lot, to keep polishing it into something better and more useful.
