very good

Very good,
I was really liked how you made use vector lines to simluat bullets going threw the air it looked good and not overdone and the ending was good.

Here are some tips you can use to make sprite animations more detail...
When the are shooting make a small little yellow bullet casing that and tween them so the spin out from the gun and fall on to the ground. You can see an example of this in my animation "Sprite mafia 3"
I have alot of high qaulity Gun sound effects on my website if you want to use in your next animation.

Ya this is shit

ya this is bullshit. Sprites aren't meant to mixed with Vector and stretched liked that.
The sound effects were horrible also.

If you wanna see something that should be in the MS collection
Check out my Metal Slug War one...

Cool

That pretty kewl dude. But the GUN sfx suck. I can think of frew places where u could of got better ones. (like Video games) are a good place to rip high quality Gun Sounds../

Cool

Dude thats pretty fun. But the graphics are not too great.
Not to complicated, entertaining, great way to burn some spare time.

Projector is no lag

This has a much higher frame rate and runs more smoothly if you turn it into a projector (.exe) file and play it on the desktop.

The style was unique in my opinion. The sound was good.
Some parts of the first level were a bit hard. This will turn away a large part of your audience to quickly as they'll get frustrated.
