I thought I would check out your other game as you suggested, and I got to say this is pretty good! It definitely has the look and feel of an old atari game, it controls well, and the music isn't bad.
I did have a little trouble with the large size of the frame, but I did manage to get the game playable by editing the page source and resizing the game to 960 by 560. I know you lost the source files so changing that might be impossible, but I thought I'd mention it just in case. I would have gone fullscreen, but apparently fullscreen functions aren't available to me.
But yeah, this was a fun game with challenging gameplay and a solid idea.
