When it is used people can try to hack it, not sure they will be able to figure it out. We set it up so that it works in a series of steps but in a complex pattern. If you get even 1 step or 1 letter wrong the ending result will be a pile of gibberish.

Thats one desirable property but this still doesn't ensure any security at all if your algorithm itself is broken.

Basically what I'm getting at is that hiding it doesn't make it any more secure; if it cannot hold to public scrutiny you're only delaying the inevitable by hiding it. Also as someone who recommend encryption to various clients I would be absolutely againsst any client using your crypto purely because it is not mature and cannot be criticized.
