I did not care for this. I guess I'm not that familiar with River City Ransom. I'm more into Double Dragon, so that ending was pretty cool. Then it was weird with how Mario appeared. How are they in the same genre? These songs have been used too many times before.
The sprite work was nothing interesting. There's just nothing that makes it stand out. I can appreciate how I rarely see cartoons with all these characters. I guess the length wasn't bad. It was just bland for me.
