Such great work! You got talent, but you're problem is finishing what you started.
The intro is tacky, instead i would of had something ATLEAST like... "today is a peaceful day but luigi is pissed off because yoshi looked at luigi wrong"
The fighting scene though is SUPER COOL, I couldn't of done anything like that I just dont have that kind of epic fighting imagination like you.
Sprite animation is kinda dying and I thank you deeply for keeping it alive, I just hope you can finish it and make it completely awesome.
