I just finished 5-4 for the first time and it’s probably the most confused I’ve been at an explanation as to what happened. I understand that this case is doing a lot of setup for 5-5, and if this stuff is further elaborated on, then I’ll shut up about this. But the whole switching the launch pad and museum to who was where at what time really was throwing me for a loop. Could anyone maybe explain it a bit better without spoilers for 5-5?
