This project is simple -- first to 30 points win. There are 3 characters to choose: a person with normal skills, one with great attack skills but weaker defense and the other one is vice versa. It is up to your favourite to choose the character.
This project is actually incomplete in details, and there are many ways to remix it. I've completed the core, but the details need your imagination. I look forward to your impressive ideas by remixing this! You may also share your impressive ideas through the comments function.
