I was a little lost in the beginning. The tutorial told me the keys, but didn't tell me what to do. After about 5 minutes of throwing the knight into the abyss I noticed that you can move the horse clip. Some red arrows and text would be greatly appreciated, since players are dumb.
Also the king kong level was super difficult. Was the pool supposed to stay filled after you put rain into it? If not I have no idea how one could beat the level.
