I think I like the idea of it a little more than the execution of it. I did it at first just going through 2D and hit the end game real quick. Then the next time around I went to 3D mode to collect all the items and when I went near the end, it put me in 2D mode and I couldn't access the end game without going back into 3D because the character wasn't aligned with the end game part. I also had trouble aligning the character with the 2D view. I think it might have been a bit better to make it so that when you go into the 2D view, it accepts A , D as backwards and forwards in relation to the camera view so that it controls like a sidescroller. That all said though, great job getting all of this done solo!
