I disagree with the Free Will idea, sentience its needed to have it, animals arent sentience, they dont have free will since they are shackled by their instincts.
I never finished this game since i started playing ti when it came out, today I just saw it there and decided to play from start to finish...
I was having a rough time in life and this helped, somehow... it just did ^^
For some reason, wall jumping seemed easy to me. for the two cube ledges, just jump to the side when you a bit under the ledge. For the single cube ledge, just jump hit the ceiling and then jump back to the wall.
You can get back to the map by choosing Menu > Quit Level, and if you've hit a checkpoint flower in that level you'll be able to start from that point again (you'll see a little blue ribbon icon on the map location).
