I struggled a little bit to figure out what to do. I made it to the room with the push button on the post, but when I pushed it, I just started moving around without any control (I'm not sure if that's a bug). Moving was a little uncomfortable.
Thanks for the feedback and I totally agree with you. The movement when there's no gravity needs a better way to move around. I was thinking about adding some form of jetpack that helps propel you around when there's no gravity. I'll be playing around with some ideas this week.
