This is something I made a while back, somehow I was not allowed to put any sounds on it, which is terrible, because sound effects could have done this a whole lot more enjoyable, and there are some flaws, like an unfinished background in the bottom right corner :)

I guess you fixed it, because it's not lagging at all.

i like it

It's laggy at the beginning because there's no preloader, or your PC's just poor. It's fine to me, amazin.

I've tried to learn preloader several times, but lazyness cought up with me every single time. Thank you thank you :P My PC looks like a jet engine, but as we like to say, it's the inside that counts

That was soo cool, I love the way you animated the speardude's movments!!

That is actually really smooth and well made! As an animator who likes to animate smooth stuff, this is eye candy.
Although there are some things that can be improved on. Obviously, the background, but for something as short as this, who cares?
Another thing is that I'm not much of a fan of immovable things, and in this case, Braum's shield. Whenever Speardude hits the shield, the shield just doesn't move at all, and it kinda makes his hits look weak. Maybe if you made the shield recoil a tiny bit at each hit, it should still retain the 'heaviness' the shield has, yet adds more force into Speardude's attacks.
Another problem is that Braum manipulates his shield too easily. It almost looks weightless. Try to put in a little bit of heft for the shield, like, Braum has to tug on it a little to raise it, and every time he stops, he has to set his shield down. Also make him try to manipulate and pull at the sides of the shield to help maneuver it. That should help show that the shield is indeed very heavy.
All in all, a very splendidly smooth animation, if not for a few minor details. Good job.

I actually had momentum and the weight of objects in mind, but didn't capture it that much :/ Anyhow, I appreciate the feedback, back to the drawingboard :)
