Nice game.
It's always good to see people improving on their previous pieces of work, and this is a great improvement.
I think it is a good game, which is 'front page' worthy - if you could just fix a few things.
I don't particularly think the previous suggestion of a 'High Score' board will help, but i think, if you just lay it out a bit nicer.
Make the menu's be simple, with perhaps like... challenges? Like 'Shoot the limewire virus that will fly past' or 'Shoot 100 red windows icons in 2 minutes'. Stuff like that (you could have the normal game ontop i suppose).
And make the game a bit more laid out. For example, don't have too much going on at once, just have your gun, and the things floating past. Thats it (maybe a timer of course).
Finally, i think perhaps just a few cutscenes of animation -
And then you've got something front page worthy.
If this review is sounding critical, i apologise, it's not meant to be.
You've got a good talent for making games, keep it up. I look forward to seeing your further work and improvements.
