I would like to echo these thoughts - I felt the same about the tools effectiveness. That said, the presentation was great even if I couldn't trust some elements. I think one way to deal with this is to tell the player the foxes are moving around, and make one of the tools a 'pulse' that gives an accurate reading but its only accurate and visible for a few moments, making the player feel like they are triangulating the foxes positions.
thanks for the suggestion! i can see how adding movement and a pulse tool could make the gameplay more engaging. my original intent, though, was to focus on the gambling part while while also sneakily teaching a bit of statistics. i think there's room to refine the balance while staying true to that idea. i really appreciate you sharing your thoughts!
