It seems that units to be placed "spawn" at the front center of the placeable area. If I placed two units next to each other at the forward of the green box, the following units I went to place would initially have their shadow "stuck" up in front/between the first two units, though I found I was able to move my mouse up by the shadow, and pull it along the front to one side or the other, and get it out to wherever I wanted to place it. So no huge deal, it seems.
I might have gotten another bug where I got stuck placing a unit, but I haven't figured out repro yet. (it had to do with trying to unplace a unit, and getting it stuck to my cursor with no shadow on the field, and then I was only able to exit to menu at that point) This may be related to the previous- perhaps when I placed a unit front and center, the next one got stuck before it even appeared, or something like that. I might post if I figure out anything concrete.
Otherwise, pretty interesting. I've had fun with a few different strategies, and might consider buying. We'll see.
