I don't watch Eddsworld, but I still think I should have been able to tell what was going on more than I did. The problem is, you don't show tge right things happening. Dude goes to get the newspaper, doesn't open the door, doesn't pick it up, just suddenly has it and throws it back. The villain guy isn't actually shown getting shot. Why'd he even attack them? Where did they go to look for the murderer? It took me a while to get the 911 thing cause the operator on the other side never said anything and I thought they were asking for money. You need to show the important things and not just the characters' reactions to them and you need to follow a more logical plot. The animation needs improvement, yes, and the text needs to look a bit better and not flicker, but most of all you need to make sure we know what's going on and try to come up with a story that isn't just random things happening. You could also add more sound effects to enhance the experience.
Overall, yes, it's a low score, but nobody starts out perfect. Just keep at it and you'll improve!
