I remember being decent at CC as a kid & playing it at Fat Darrell's Pizza & Arcade.  One time, I got a good game going & a crowd of a few people watching.  My dad was watching me from afar & told me that I had quite a bit of body english going on while whipping those joysticks to & fro!
1st question: isucamper, are you me?  I too stumbled across Crazy Climber at CAX.  I didn't see it till Sunday afternoon, when my headache was raging & my arms & wrists were sore.  I could get only a few games in--it hurt too much!  After rediscovering my love for Mad Planets in the competition, I vowed to pick either MP or CC if I win a competition again.  Thanks for reading my mind!
2nd question: why do the red girders & dumbbells sometimes knock me of the building & sometimes don't?  Random luck?  Some algorithm that I'm not grokking?
3rd question: what makes the balloon near the top of the 2nd level sometimes be grabbable & sometimes not?  I got it only once out of 8 or so games.
4th question: after walking away from CC @ CAX, I thought to myself, "Boy, CC really has the most intuitive set of controls of any game."  So I'm shocked that some people aren't getting the hang of it!  =O  Oh, that's not a question--let me rephrase.  Why are people not finding CC's controls intuitive?
5th question: how much electricity can your climber absorb from the haywire Nichibitsu sign?  I turned colors when brushing the loose wire & once turned colors twice & then when I went back to my normal colors, my head stayed black.  Singed?
6th questions: isucamper, you don't list any DIP switch settings--you just say to use default settings.  Please elaborate.
7th question: is 150,900 a good score?   

Thanks,
