Live on https://gamescape.app/ are the measurement tool and real-time laser “pen” indicator. All connected users have their own color “pen” and can draw on the map to highlight or annotate. Everyone sees the drawing happen in real time. The drawing only stays as long as the person is drawing (holding the mouse button / touch / or stylus).
Originally this was going to be a laser pointer, but I felt the ephemeral drawing aspect was more useful than just the single indicator point (or point with trail). Curious for feedback.
