A bit of a strange grid, in that I got all the groups sorted, but then didn't score any bonus points for my offerings in the group identification. I don't think I've ever done that before.
My detailed feedback:
- It didn't accept "make up" because you wanted "make-up" with the hyphen.
- It didn't accept "parts of a tent" for the parts of a tent ... I'm somewhat confused by what you mean by "structural elements".
- For Ball, Bolt, etc, I went for "lightning", and this was given as wrong. I suppose that's fair as it only matched three of the clues. Dungeons and Dragons is very niché and I was never getting that.
- The Cyclops line had some very obscure parts to it but I suppose was gettable.

Cheers anyway. Looking forward to your future grids if you leave out the very obscure lines :)

Sort of annoying that it didnt accept make up without the hyphen.
