Solo Chess puzzle

This may help you:
Nf3xd2 - Nd2xBb3 - Na1xBb3 - Nb3xBc5 - Qc6xBd5 - Kc4xQd5 Re3xRc3 - Rc3xBc5 Kd5xRc5 -or many other possible move orders... Maybe you was a having a "complete brain fart" (lol) 'cause you underestimated the kings' power...? it's been a while since your post. If you're still playing "solo", maybe you would like to give me a short answer? I've discovered it a short while ago, tough it's on chess.com for a long time already, and I must say, I've become a total fanatic (10h binges!!!) quite interesting stuff...
But I'm often expiriencing glitches, they still were able to fix it (suddenly the pieces are frozen and stuff)
BYE
Thanks for your comment. The key move I missed was Kxd5 to open up Rc3xc5 which builds the 'bridge'. Thinking back, what got me stuck was thinking that it's up to a knight to do that (just glancing at the board that still looks like it should be the natural solution), also I got into a pattern of saving king moves until the very end.
