Black hole looks so pretty! I think the stars are shooting the wrong way if you want them to help it look like we're falling. As a physics teacher, I was super weirded out by the objects flying a way from the black hole. They would get sucked in too! Like others said, I would've liked to be able to move more. I couldn't even tell I was falling in the beginning because there was no feedback for my motion. Definitely a a good foundation!
