Everything I've come to love about HI over the past few months is being slowly eroded away through the frustration of trying...and failing...at getting the fucking Yumiko easter egg! Given that even a blind squirrel can find a nut, one would think after over (conservatively) 400 attempts and WELL OVER 4 hours, I would have triggered it by complete accident by now, but nothing.
If you managed to get it in 500 attempts or less I congratulate you, but I'm pulling the rip chord and crying uncle. I give up.
