Fun idea, and I liked the cat art/theme. I wish the camera would follow a little further behind, or zoom out as the characters separate. I got stuck a lot because the camera was too close and I couldn't see one of the two characters.
Also I think it could be fun if there were another way to lose besides breaking the link for 5 seconds. Maybe some kind of timer to complete the level? Or maybe a level designed in a way where you *have* to separate the characters in order to progress, so you end up doing it very quickly to avoid losing. It just felt a little too easy to keep them linked.
It's super ambitious to do 3d like this in 48 hours, so mad props for that! Well done!
