how come anyone in the world can clear everyone's scores..........???

You move left and right, trying to avoid zombies and trees. That's it. Why half a star though?

Well first off, the character's running animation is just two frames. But even those two frames are pretty bad, because the lighting of the character changes in each frame. This really made the character look bad.

And then you got the trees. You can see that they're moving down and that the ground isn't. This is pretty off-putting if you ask me.

On top of that, you got the music. The track is really small and it gets cut off when it's trying to loop. This is really annoying honestly.

Lastly, I would like to mention a nitpick of mine: the ammo section on the bottom. This isn't really a flaw or anything, I just wanted to mention that it really sucks that it is there, because (as of now) it doesn't seem like I can shoot in this game at all.

Judging from your author comments, I can see that you're open to criticism. So I hope my criticism helps you to improve the quality of your future games!

not bad is too simple but not bad its funny

Decent potential here. Some of the pacing seems a bit off though. The Zombies should at least be at the pace of the trees unless they are running backward. The tree pacing also seems a bit fast for the overall character movement, but it's a good start!

The highscore system as a pop-up was a little odd as well. I would much prefer to type something into the game window.
