I liked how you had to watch both the balloons and the crate when navigating tight spike corridors. I also liked how you manage horizontal movement by strategically popping. However I felt that sometimes the crate would feel a bit slow especially when I had to wait for the crate the settle on the landing spot.
On an unrelated note I wonder what that crate is made of that it can survive a drop but instantly shatter at the tap of a spike.
