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.
Good luck.
