This is very cool. I also did the same thing, solved the cube in 1982 when I was 7 with no algorithms. I posted the method somewhere else on this forum. Solve one side, then keep breaking off a corner and putting it back in a different way, hundreds of times, until the bottom corners magically solve. Then solve the edges intuitively with keyhole style. For the final M slice, keep breaking off an edge (keyhole) and put it back in a different way until the M slice is oriented, then permute M slice intuitively.
