I think given the gameplay you could for sure design this in a way to convey the mechanics without much text. Since the city is based on tiles you could easily reduce this too to fit the jam constraints. As it stands this far exceeds the amount of pixels allowed to be used, though I think you can fix that.

I think you should try to display your variables as icons on the screen with number next to them instead, it would take up less space. Then maybe allow the player to scroll through the city area with WASD so you don't have to cram everything into the small screen all at once. I would also just round the numbers down too so it takes less space on the screen. I think the compromises are necessary considering that this jam is about seeing what you can do with the limitations. So compromises are needed.
