The hint Elfie gives to rotate the blocks should now properly indicate that it's double tap (double click) and not just tap.
Added middle click as a secondary action to rotate the blocks. This is just a single click at the moment.
The hint Elfie gives to rotate the blocks can now appear in level 3, 4 and 5. (Only 3 previously.) So players that might have accidentally completed level 3 are more likely to still be able to get the hint.
