Completely agree!! I wish I had implemented it before the deadline. I was thinking of a scoring system, or a win condition when the player maxes out all three stats.
What do you think - would you do one or the other, or both?
I think going for the classic arcade setup would be perfect - just show a score that increases whenever you destroy a ship. Maybe you could award a score bonus whenever you max your stats and then reset them, but in my opinion an endless mode would suit the game better than a set goal
