Really well thought out game, an amazing use of the limitation. Many games find a way to avoid the limitation, but I've always found working around it to be better, like this. You saw the limitation and built a game idea from the ground up to use that limitation as its core, creating a unique and interesting game concept.
Some minor problems I had, besides the ones already mentioned like not seeing the people's path, I found that the area to click the icons of the troopers is too small, though it appears to be accurate with the sprites, I would've liked for them to be bigger so I don't have to click the exact rectangle of the sprite.
This submission is really solid, probably the best one I've played so far! If you end up making a more fleshed out version, I'll definitely check it out if I find out about it.
