Pngcrush just isn’t a very good PNG optimizer. Using OptiPNG or TruePNG, I managed to reduce the file size of your example PNG file by about 26% (from 33.5 KiB to 24.6 KiB).

And running PNGZopfli on the result of the TruePNG output gives a file size of only 23.4 KiB. Note that this is with the various max settings of both TruePNG and PNGZopfli, and running this takes a long time, but even with the (very fast) default settings we get a comparable file size – 23.5 KiB.
