I agree with CyberDevil (I broke my rule). I think the best thing about this was that it was pretty easy to understand. It didn't really matter that much, because it was quite difficult. I couldn't help but think it was because I used a laptop. I still can't say it's a bad game. It was pretty challenging and had a fairly unique design.
I always look for those things in games. I don't think I've ever played the Vectrex game you're talking about. It sounds as hard as this. It's good that you have nice mobility. I think the music's a little too loud.
