Is it possible

[Gooombaa]

Hi. Here's my level design

I have 6 doors in a castle room. 5 doors lead to a level, while 1 leads to a boss, however is it possible to make it so the door is locked until you beat the 5 levels or do you have to make it star locked? That way it isn't a forced 100% game

The only way to force the player to play the first five levels to unlock the boss room is using stars. How to do it: The warp for the boss room have to be locked with 5 stars to unlock it and the other levels must have a star exit.

If you don't want to use stars, you can do some complicated stuff where you make a bunch of copies of the HUD room and a bunch of copies of the levels where each different version sends the player to different versions based on which levels have been completed so far. In concept, it's not hard, but you would end up with 120ish copies of each.

So... you would be better off using stars if possible.
