I like the premise of the game and I also appreciated that you added those controls to give a feeling of floating in space (even though I did have some trouble navigating).
I don't mind the idea of the maze but it was just a tad too long for me. Maybe add some checkpoints so taking a wrong turn isn't so punishing? Or just make it shorter?
I did manage to power through it though and reached the generator room where the generator was missing. I didn't know what to do next ( and really didn't want to go back all the way through the maze again to see if there was anything else back there) so I quit.
I think with a few modifications this has potential and could be great.
