I always find rulesets like this very daunting, but I spotted the trick fairly quickly and then it flowed very well. Really enjoyable puzzle, thank you.

Really cool constraint! I'd love to see another puzzle with a similar constraint.

Really nice puzzle! I love the positive constraint where all indexing cells are marked, and some really nice uses of the negative constraint throughout.

Fun puzzle! It took a little bit to get my head around the rules, but it was a smooth solve after that.

Took me an embarrassing amount of time to understand the break-in but after that it flowed very nicely, thank you for this puzzle!

This is a really nice puzzle and a very interesting rule set. Not too challenging once you realise what the rules imply, but it was a fun solve

I had the exact same idea, but then I was pointed out to this puzzle :)
You executed it well, it was fun and smooth solve :)

Wow! As a new solver, it took me a while to get my head around this ruleset, but once I did it was a very interesting solve! Thank you for the puzzle :)

Empty grid, simple rule set. What's there not to like?

I loved solving this, and the grid told me I'd done it! But my solution code was wrong. And now I've found two digits in white squares indexing each other. Back to the drawing board :(

The negative constraint made for some v fun logic---thank you!

That was weird, but a lot of fun. Really cool idea! Thx:)
