At first, I was confused as to why the rating wasn't higher. This feels just like the original game! I now realize it was because it was mostly just the same stuff over and over. I'm still glad to have come by this. It really does capture the spirit of the original game. I don't recall the earlier entry here.
I don't know why you could make the picture bigger. This is the first time I've seen that on a game. Is that something new here? I'm glad it was easy to understand. It was pretty fun just to kill those guys.
