It reminds me of .io games, I think because of the simple background and the endless nature. It's fun! I didn't have any visuals for selected Jailbirds, but if I control-Click and then Shift-Clicked, they did move as directed. And it's very amazing to do this in Vulkan as your first game.
I assume the lack of selection visuals is a bug, since they were popping up for other reasons. So my recommendation would be to make the pan speed increase as you zoom out so you can look around the map more easily.
