Be careful when you go fullscreen the bottom part of the game is hidden, it took me ages to find my workers because of that.
Other than that it's cool, responsive but it's a bit grindy.
still a nice entry!
So the thing with canvas: the default mode in the canvas scaler component is "pixel perfect mode", which doesn't adjust with resolution. You need to set it to "change with resolution" (something like that) and set the resolution to 1920x1080 (if it's the default resolution of your screen.) You might need to rearrange your interface tho
