Sorry, but "nice eyecandy and gameplay" does help me actually. Until now my levels were usually levels that had a pretty bad gameplay, so that review would tell me I actually achieved my goal, which was creating levels with decent gameplay.
And unlike most of you (at least it appears that's the case) I find a "nice work, you really made a few good levels" nicer than a 2000-character review with the boring standard pros/cons layout. It's almost looking like they are computer-generated.
