The mechanic itself is really cool, the implementation needed some tweaking. The meter depletes much too quickly for the average player. Also not sure if it was a bug, but the cursor was massive during gameplay and where I tried to draw the line was offset from the center of the cursor. Sometimes the paths just wouldn't show up. Still a cool concept and I was able to complete with some trial and error and brute force of retries.
Could be easily expanded upon though with these fixes!
