I bowed out a few days ago after getting about 250,000 without losing a man yet. Followed this up with suicide mission after suicide mission. It felt as though I was repeatedly trying to kill their bullets using my ships. You should have heard the names I called myself. I ended up with about 350K, disgusted with myself and wondering if the Mame version is harder than the arcade version... Is it? Oh, and what's with that random bullet that falls from the sky every now and then at around wave 25. It almost killed once because the wave was over and I had let go of the controls for a sec.
I think I'd be back in form but am running at of time. The same thing happened with Joust and QBert. I starting to whoop its ass again in no time. So far Galaga is handing me ---my bottom--- and it doesn't look like I'll be bouncing back any time soon.
And Yes, Defender would be a nice choice.
