Line 53, if you move the mouse beyond the canvas, it will fall out of the map range and make tileCountY undefined. It either needs a fallback, or a constraint on mouseY tileCountY = int(map(constrain(mouseY,0,height), 0, height, 2, 10));

This should be resolved now. I ended up implementing your proposed solution. Thanks!
