I am fairly disappointed in the last four levels. you could have done more than just changing the direction of the pivoting platforms. I would have given 5/5 since I love this series of games, but that last bit made me drop down to 4/5 for lack of creativity on the final product.
agreed it is about luck, but the degree of skill is in the patience to wait for the sway to pull the tower back so you can place the next piece. good game 4/5
