Probably not the worst game I've ever played, but definitely the least fun. Everything about this game seems tailor-made to make you hate your time with it. I genuinely cannot find a single positive.
The market idea, while possibly decent in concept, is an atrocity to actually play with, same with the city. They just scale to "Screw you for trying to play" heights way too quickly. The whole experience just felt like an exercise in scarcity where you never will enough money, energy, engineers, or anything really to do what you want to do, which if intentional, then yeah you have a fine art piece, but that doesn't save it as a game.
I wanted to play through every game in the jam to 'completion' even if I hated them just in case they get fun at a certain point, but this game broke me. I just can't keep going. Currently I'm stuck grinding research for the 8000 research upgrade that makes coal plants produce more. If the games gets fun after this, I'm sorry, but I just cannot fathom that happening, so I'm jumping ship here.
