Hi, there isn't much to know:

Endeavor has 12 exits and they get harder* in the back half.
*Difficulty is subjective and will depend on your experience.

One of the exits has some cape in it, you should also know 
how to goomba jump and other kaizo tricks. I recommend 
playing "Learn 2 Kaizo" or "Learning to Fly" if you feel 
stuck with anything. Those are good tech resources. Another
solid option is "2 Kaizo 2 Learn".

Vanilla sprite behavior knowledge will also help a lot.

There is a clear video on my YouTube channel, and if all else
fails feel free to use save states. I'm not one of those
"save states are cheating" people. Please play my hack 
however you like. :)

Everything in the hack is in it because I personally found it 
fun, and not to arbitrarily make it hard. I hope you have fun
too, but if not, thanks for trying it out.

P.S. If something fun or cool or interesting happens to you
while playing, make a clip and send it to NixKillsMyths#6454
on Discord! <3
