Great entry and ideas for a very cool and innovative game! Def needs more time to be imagined and implemented but this is only a two week jam so I get it.
I love how you've integrated a lot of things together and I like where you have taken the whole 2d/3d switch along with other elements.
Movement and collisions definitely need work tightening up; I was getting frustrated falling in holes or not hitting a platform that it looked like I did. I'm guessing the collision object doesn't change much on the character when switching, etc. It seems like it is too small for the character at times.
