Decent puzzles, but the physics make the controls extremely annoying.
Level 16 was kind of tedious, since you can't easily plan ahead. I seem to remember 14 being annoying, too, but I can't replay it without going through the whole thing again.
For all those whining that you should be able to cross boards when they don't exactly line up, you do realize that would make the puzzles trivial, right?
And for people becoming trapped, I never found a situation where I had to reset in any of the 32 levels. There always seemed to be a way to get anywhere from anywhere else.
I completed all easy medium and hard levels, then when I completed the first extra level (31), I wasn't able to select any new levels, i.e. 32. And, I just tried it again, with the same result. So, unless the extra levels are unlocked some other way, I'm stuck.
Regarding the F's or f's, in a quiz that is so dependent on specific wording, I'd disagree that it's a technicality. I'm not logically wrong. The writer could have simply asked "what is the total number of F's and f's in the sentence. Aside from that, the f's question already appeared in an early version of this quiz, so should not have been repeated anyway.
Your question about the race assumes it is either a single lap race, or a race that doesn't take place on a closed circuit. For any number of laps greater than 1, you can certainly pass the person in last place.
