+        <_manual>Looking at the rockwall, you can see a sparkle somewhere. Move the mouse cursor next to this sparkle and use the mousewheel to zoom in.
+If you zoomed in at maximum, a gold nugget will appear at the position of the sparkle. Click on the gold nugget to collect it.
+
+Having collected the nugget, use the mousewheel to zoom out again. If you zoomed out at maximum, another sparkle will appear, showing the next gold
+nugget to collect. Collect enough nuggets to complete the level.
+
+The lorry in the lower, right corner of the screen will tell you the number of already collected nuggets and the total number of nuggets to collect
+in this level.
+
+Have fun! :)</_manual>
