WELL THERE YOU GO! You figured out a lot of the stuff i pointed out yesterday yourself, well done :)
Still lacks a lot of stuff though.
So now we see the other points I made on the review for your first game : lack of raw "power".
The gameplay is very simple, and not all that fulfilling. While the score you added does a LOT for the game (since the player now realizes what he's doing) it still is very repetitive since the whole adventure can be resumed to : move in circles in a small perimeter and shoot.. well not quite, but not far from it
So yeah, now we actually get that SOMETHING is going on. And hey, we are intrigued for a small while. But it just doesn't suffice, since the gameplay and (very small) scenario repeats itself WAY TOO QUICKLY
And again, the lack of music or sound effects doesn't help, sorry about that.
Also, while I do not care about the graphics too much in most games, you definitely can't say "doesn't matter, they will stay for the graphics" in this case.
Hey, big improvement though! I actually think this should definitely stay here, so I'll give it an encouragement score
Keep it up, I'll still be looking at your next games :)
