This is SO intricate and elegant! Incredible setting! I'm impressed that it keeps the consistent difficulty until the very end :)

@Franjo: Thanks for giving it a go and the lovely feedback! Aha, you're right about the tromino vs triomino thing. Apparently a triomino is like a triangular domino. I'll change it on this puzzle page (but I'm too lazy to update the link) and add the missing tags, thanks! :-)

Great puzzle! Love it. But as far as I know these pieces are called trominoes, without i.
