Example:

Map 2.

Equip Holy Mace.
Then go over the hunter icon, BEFORE going over the equipment icon, result the tutorial cannot then advance, as you cannot then hover over the hunter icon.

So far I have been defeated by the tutorial 3 or 4 times through bugs. Another example, map 1, move a unit to the selected square, the square is outside it's movement range, thusly the tutorial cannot advance.

Map 2 Use Earthquake, map is too high, mouse pointer disappears, cannot advance.

Minor glitches.

Sometimes the dragging icon remains, even after spell is dragged. Doesn't stop tutorial, just looks odd.

Example of the minor glitch.
