I really enjoyed your game so inspiring, I'm even trying to make my own 3D bitsy game but I'm struggling with the exits and endings, don't seem to work with an other room.
Thank you! Bitsy 3D uses a stack of 2d rooms to make 3D scenes, so maybe you're placing your exit point on a higher level of the same room, instead of the next 3D scene?
Best of luck to you - can't wait to play your game!
