Very fun! 3* for a doppelganger, 4* for all sudokus. Great flow here!

Great puzzle! I am not too familiar with the doppelganger rule and I learned a lot. I really liked how the outside cells interacted with each other. My only tiny criticism is that the rules should probably explain what the outside cells are for. Thank you

This was the second Doppelgänger puzzle that I solved, having done one by ChinStrap yesterday, and I am really liking these! Excellent setting, thank you :)
