The game was so good till the leaf-head because I died going back (stupid me),
so I restarted from the last checkpoint but I was not able to go over the rock because the big one can't jump and all the piecies remained on the left side of that rock, so actually I just can't destroy the rocks to go through them because the 1/3 pieces can't destroy them so I can't go on with the game and I'm not going to restart the whole game just because of this bug.
Sorry guys, fix it for the next players if you understood what I was talking about.
