Terrible wall. Badly made, nigh impossible to solve.

Very well made! I thought it was impossible until I started to think logically. Great wall!

I'm in the middle of the other two - nice idea but fairly impossible.

I liked it! A novel idea.

Sorry, agree with UBone, impossibly and wilfully difficult. No fun at all

Clever wall!

I liked it and solved quite a lot of it

really liked this wall.

Very clever idea.

Not sure why one group wouldn't let me have "wall".

A clever idea, though maybe could have been presented/executed better.

Ii may have been easier for me if I'd known about iwahig prison- I thought this group definition was still a bit weak- pink floyd song, wall doesn't exist? No way I would have spotted a commonality amongst a jumbled grid for those. Bit confusing but good initial concept.

Bit too clever for your own good my friend.

Confusing mess i'm afraid.
