600+ hours and counting on Steam; the Vita purchase was just for the hell of it, really. Suffice to say that I love that game and the obsession runs pretty deep. There are races tonight on Twitch, incidentally - you might enjoy them.
Congrats on clearing the crab route, that takes some doing. I nailed the crab 2 route today and feel pretty satisfied with that, though I do genuinely dislike the crab boss fights. I was happy when KawaseFan pointed out that 54 wasn't an end route of itself - it means I just need to learn to clear 59 and 33 semi-reliably and then those last two routes should be completable, I don't think there are any other "problem" fields en route, though I guess I'll find out.
