How to get the spike kill : do the same walthrough's configuration, play, move a rocket a little, play, move a rocket a little, play, move a rocket a little,...
A lot of features to fix : we cannot cancel selection on fortress attack, shrines are too overpowered, buffs should be shown by a small icon. For the tourmanents, wait for shrines and it will be a piece of cake.
Congratulations! :)
