I liked the idea, but it kind of started falling apart in the second half.
There are two full on softlocks I found:
If you try to hop into the elevator in The End level and miss, you fall down into a canyon where you can't move other than turning.
If you press Z at any point during the final level, you get swapped to a camera, but pressing Z only switches you to the other camera and you can't back out of it, meaning you have to restart the level.
In the last section with the forced perspective, if you walk out of the last doorway and then back in, the camera switches back to the hallway cam and you can't change it again. It's only a few steps to finish at that point so you can do it blind but, still annoying.
As for the end, I can't tell if it's bugged or not? It plays the cutscene, then returns me to the camera with no control over the little dude, I can again switch between cameras and nothing else.
