How about more than five stars, how about unlimited stars? Here's how it works: after one star is taken another appears somewhere else! So you can have an infinite number of stars. There would have to be a setting to turn this on or off in the editor! I just made a level and got really sad about taking one star out (because I needed it elsewhere).
@Chris Hester Then the level will become unsolvable But I do have an idea for this setting: Maybe there can be a speedrun challenge in which players must get as many stars as possible in the same level within a specific time limit. And the winner of the challenge gets a prize or something.
Oops I hadn't thought of that! But two solutions come to mind: The player sets the total number of stars in the game, say 20. The card will show this number so the player knows how many stars to get. You simply add the winblock to end the level.
