I'm thinking this is the same as the Galaga game I used to play. Dang, that brings back memories! Anyway, I actually thought this was pretty good. It really is interesting to see these different designs. The original game, is of course, better. Then again, I haven't played the exact Phoenix game you're talking about.
I thought the sounds were pretty cool. There really were some nice colors in this. While it can be too difficult (at least in comparison to the game I'm thinking of) it's still pretty nice. A pity it isn't that popular. It's at least decent.
