I played several games on the Mac IIci today, with a nice condition AEK II keyboard. Maybe it's a tiny bit easier than what I'd been experiencing under emulation, or maybe it's the keyboard, or perhaps all my practice is just starting to pay off. I had several decent games, including one where I reached 130-something rows cleared and that involved an extended period of survival at level 10. Since the difficulty doesn't increase any more after that, I think my scores could improve significantly if I could just get a tiny bit faster with my fingers. I can just barely keep up with level 10 when I maintain hypnotic levels of concentration, but any lapse in focus or a single missed keypress and I'm doomed.
With version 2.9.3 that I released recently, I noticed that the music glitches out every few minutes and briefly plays some garbled noise. I don't remember ever experiencing that before. Maybe it's my computer, or maybe I introduced a bug in that version. I need to install System 7 so I can go back to version 2.9.1 and see.
I also spent some time experimenting with the AI Autoplayer, which is only enabled if you have registered the game. There are two AI levels, "fast and dumb" and "deep thought". As I recall, fast and dumb only considers the current piece and the next piece, while deep thought also considers all the pieces that might come after the next piece. I watched deep thought for a while, and it made quite a few moves that looked sub-optimal or even like outright errors. Fast and dumb actually performed better.
