Hey thanks for playing it again! Yeah i designed that last stage to have about 3-4 different ways to the end, but you'll generally be guided along by whatever the last new ability you got was so you dont get too (hopefully) lost.
Thanks for letting me know about the platforms - we did an entirely physics based solution for that instead of parenting since we enforced a lot more control over the rigidbody than would be typical in order to get tighter controls for the main character.
Unfortunately it seems like a tweak we made to our system later on added that little "bump" at the top of the platforms movement resulting in you technically not being grounded for a split second and therefore not able to jump. Will definitely look into it for a post jam update!
