I know it's beta already, but if you're still interested in my thoughts on the game..
it's really fun. I definitely want to end up with a copy of it. I don't like emulation very much and am looking forward to trying this on a real machine. I prefer the gorf-shot canceling fire to regular SI and the sprites look great. The powerups add a lot. At first I thought the player ship's shots were a bit too slow, but I've played both Gorf and the original SI since then and changed my mind.
What i'm not so into: the whole screen changing colors. I think a border around the screen that was black normally but changed color to reflect the play state would be better? That said, it's actually somewhat of a feature that the screen changes because it's hard to see what's going on then. Maybe it could be kept for one of the negative effects?
Also, maybe good powerups could appear a little more often? I find myself mostly just avoiding the special drops as if they were regular shots because they're often negative. Which actually kinda reminds me of arkanoid like terrain mentioned. Silvio, did you have this in mind while working on rainbow invaders?
