As someone else mentioned the cover does not do this game justice.
Took me a while to figure out how to do the big jump and then got stuck a little further on after the next save point I think. The spikes were somewhat frustrating when trying to jump over them bumping into the side. . I don't know if it would make the game too easy but having the player only collide with the spike when they are moving in the opposite direction to which the spike is facing would make it easier.
