To be honest I kinda got stuck at the volume adjuster for a really long time before I just brute forced it
also I got stuck on the platformer section
When you pressed the switch character button did the border change color? If you're green you're Diere if you're red you're Lufo, you can't move while in action mode. Also the only way to proceed the level is if both players have went to the exit, which yes the exit has missing image assets when a player enters it which I did not know how it was not finding the images
I may be at fault that I did not also clarify that, but the other things I need some more detail as to why it may not be working
