This is really nice, played this for a while and almost was able to open up the entire map (which seems to be the objective) but I ran into an issue where on my resolution (playing on a macbook air 13”) the cells were offscreen and I couldn’t zoom out any more or scroll the camera far enough to be able to see them.
Besides that issue everything worked great. I had a lot of fun playing this. Good job. My game is linked below if you want to check it out.
