After quoting the post and going to the page where the images are from, I found out that they are 404. Link them to your filebin or another image hosting device instead.
This hack felt kinda generic, but at the same time introduced the player to some of the most difficult abilities. You could have done more things with it than the overused stunts we see everyday; imo, Kaizo isn't just about shelljumping, for example. If I could give you a suggestion, it's to add more things to introduce things better, but it could be me. It's still a nice hack.
