You get skill points from leveling, higher difficulty, more experience from winning, more skill points, and thanks chaneldogg, I think a got a comment before from someone else liking that I commented =)
Duh, that's the point, u suppose to start with the beginner modes then as you get more skills from the skill points and get better at the game, you go to a harder difficulty to get more experience, more skill points and vs a harder opponent
Well, basically if you haven't read the instructions then what you do is in-game you use your skills in try and get atleast 3 of your laser's power 100 more than your opponents lasers power
