Thanks for the feedback and the encouragement, I really appreciate it.
As for the "impossible" level 3 jump it's obviously possible, otherwise it wouldn't be in the game :P
The more you press space the more you jump. Oh and the hook only goes off if you are not too close to what you are aiming to. This was done because in fact your arms in this cases are inside geometry but it doesn't look like it since I used camera culling masks.
And again thanks for the feedback :D
