The Dink Network

I've been replaying this game recently, and I'm stuck. The yellow key is the only key I don't have, and I can't get it because Dink can't turn and punch fast enough to catch the blue arrows (and even when he can, punching them only works rarely.) Does anyone have any advice for how to do this? ( I don't recall having a problem with this before, so I'm not sure if it's a new problem or not...)

You could just tank it I guess.

Actually, how can you not tank it if you have all the other keys?

I can make it past that round, but then need to luck out in the final round. Too many blues and I'm dead without a chance. This has happened the last three times I've tried, hence the asking.

Well, I got it. Just ground my way up three levels, put all the points into defense, and tanked it.

Now I just have to beat the dragon, the zombie, and things like shut off the power and stuff. I also want to work out what the point of some of my items are, particularly the feed, alcohol, moonwalk glove and sixth sense, as none of them seem very useful...

Did you have anything else open while doing it? Also if hitting is a problem you could try to use the "debug" option when playing, though some might regard it as cheating.

Is turning off the power actually beneficial in any way? You trade most of the game's playability for some gold.
