It's been time I don't comment on a work of yours.
This level is pretty nifty and all, but I don't think you tested it too thoroughly. It's a bit too easy for a penultimate stage. For instance, you could have avoided the urchin at the beginning and made the chuck clap normally so you go under him faster without the switch. I could also skip the first P-switch bit by simply going to the left.
If you want to recreate it, it's up to you.
As I said, the level is awesome, but with some tweaks it would be a lot better. I'd personally only fix the breaks and make it a bit harder rather than restart it from scratch. You do have potential.
