Interesting concept and well made, there was a bit of clunkiness to the ui for me (clicking scan would also move the screen view, for example). Nice work.

Each dig or scan focuses the camera on that tile (within some tolerance). Maybe that's what you experienced?
To move the camera around without digging/scanning, you can click on tiles already dug (or even outside of the visible tiles). I added this behavior very late in the jam and I don't really like it. Dragging around the level with the mouse would have been much better, I think. But, alas, time was running out =)
Thanks for your feedback and playing!
