I think it might be interesting to know, but I tried visiting this webpage on Safari on my iPad and the game works! The click, drag and hold controls work and mouse-over windows stayed wherever I clicked, but I couldn't zoom in and out. Obviously, without the keyboard, I couldn't select the people and I can't enter numbers into the job screen. Also, sometimes, the music would get messed up. The full screen button didn't work and the screenshot button soft-locked me.
This is just in case if you're interested in seeing how to game feels on mobile. A couple of things not working right, but for the most part, I would say is a solid experience! It feels so much more satisfying placing these buildings with a touch. I haven't taken a look at it extensively, but I hope this information can be helpful.
