The game remake looks great. It has an appealing look and the gameplay is fine and fluid. I would work on improving the character's animation and some of creature animations (I would recommend to hire a professional animator). Other than that it looks pretty cool.
It's a pitty about Konami. This is my advice: keep the game structure and just rebranch the project (change the name of the game and the characters names, etc) and you will be able to release it even comercially.
