The levels were nicely put together, it was interesting to see some level of environmental storytelling in there.
It's a shame that dying didn't work, since it's basically just space station sim now! The physics were nice, and it was cool that you could crash into other objects and they would float about.
As mentioned below though, movement was a bit rough and I got stuck in either the wall or floor 70% of the times I moved, which was a little frustrating.
Overall though, you did some nice work. Congrats.
