I haven't played a city builder game in a while now. I got a bit confused that giving 2 power sources to a building would cause issues (would be nice to have a warning about this before placing the second power source) and I found the UI (on web) a bit hard to read (text too small).
Nice prototype otherwise, as others have said it lacks a progression etc, but for a 1-week jam wow that's a lot of complexity already implemented. And placing buildings in kind of a sandbox mode is fun a bit already :)
