Switches Into Other Levels

Is there a way to make the player need to get 5 different switches (blocks to hit) on different levels that will open a door on the last level?

make it where you must collect them to proceed

I made it so when you collide with the key it sends a message to the door it gets destroyed but when you start the next level the door resets. I want to know if there is a setting or something that keeps the door gone the whole time after it is destroyed

hmm I’m not sure

When you send the message, make it subtract 1 from 5 to open the door if it = 0.

Mailbox --> -1 --> (+) 5 —> Filter ( =0 ) --> open
