Interesting start! I couldn't quite figure out how to do much aside from building houses, and I wasn't sure what all the other non-house icons meant, how to use engineers (automatic?), or what the other two options on the left were aside from house building. There were some controls on some of the tile panels on the right, but it wasn't clear what they do - mostly just numbers with +/- buttons but no other explanation.
Could do with some sound effects and music, a little more explanation, and some UI polish and more descriptive labels.
I like fast paced builder/sims like this, so I would definitely be interested in playing it more once it's more polished.
