What defines the endings, blue keycard exit makes sense, but what about blue skull key exit, does it matter what level you exit in?

Also, would it count for two endings at once if you say get the abandoned house sale sign, then exit the level with the blue skull?

For the fake beach ending, do I need to close the clicker or just enter the beach?

I'm trying to make the first run for this category, and right now I'm sitting at 41 minutes, but I'm unsure of the rules.

• blue skull key exit is abandoned house ending afaik
• mirror world exit is separate
• fake beach ends on hitting the clipper
