in the tutorial section it says to turn around to hard kick, but in that corridor the pony only ever kicks to the right no matter what I do. It's very frustrating. The hard kick and small kick should be two different buttons, considering that they are in different directions.
I think the final boss should be selectable as a level after you kill the stage 3 boss. In no mood to repeat 12 waves over and over just to do a final boss.
