Just a reminder: You can't copyright a game mechanic. You can patent the things to do it, but mechanics are fair game. Anyone can use a d20 to roll to hit, for example. That's why GW made patented scatter dice.

As for your design, the points are the easy part. They also come at the end of the design process.

Not trying to be negative, just giving some pointers from someone who's been where you are more than once.
