Very detailed review....I love it! The player's position on the right side was intention for the goal is to stay within the camera bounds. I can understand why you would pick the bottom ones over the top ones. With your regular jump height, you can make it to any of the doors. It would depend on the where the obstacles are and if you wanted to risk getting a lower score or not since each door randomize to have different scoring!
Also, depending on which realm you'd want to go to, you'd choose that door, if you're able to get to it! I am glad you enjoyed playing through the different sceneries for it was fun for us to run through them too!
