Beat it in about 15 minutes without skipping any. I used spaz up until level 8. I was disappointed that it forces you to use jazz after level 8 (8 and 9 are impossible with spaz). The changing wind speed in a lot of the levels added unnecessary difficulty.

I was expecting a finished version of that really old WM4 in top secret 3. That one was fun, and had the same sort of feel as WM3. This one feels more like WM1 and 2, or violet's windy tests, except with fooruman thrown in.

Overall I'd say it's an average test level. Which is to say, it's better than the atrocious crap that is usually hosted online (though not nearly as often these days, thankfully).
