I did the " Separated by a Common Flame" puzzle (you're doing something funky with copy/paste so I had to right click to copy the title and all the clues).

It's fun, but I have some pointers.

1. Try to follow NYT's cluing rules, like plural clues always have plural answers. I was tripped up by "Bark pieces soaked before scattering over coals (8)" having the answer WOODCHIP.

2. It's very difficult. I solve NYT pretty handily 7 days a week, and difficult crosswords in Swedish too, but I ended up using 21 hints, and not only because I rushed. The lack of crosses makes it a lot harder to get a lock on the grid.

3. There was some questionable cluing in general, like "Shredded cabbage side at every British barbecue (8)" for COLESLAW, which I would not consider a particularly British side, and "Shallow inflatable pool beside the barbecue (8)" for PADDLING. Omitting the noun for that type of compounded adjective-noun word is fine I guess but felt clunky.

I like the gimmick itself though!

Thanks, I appreciate the feedback! I'll look into the plurality issue.
