Nice game. I like the idea of repairing the space ship and being weightless. The graphics were cool too. But I wasn't sure how to complete the puzzle.
Spoiler alert - I added the pipe, the lever, the plate on the boiler and turned the red wheel but nothing happened. The display when I turned the red wheel flickered a lot but I could see that it changed value.
There was a cube that I couldn't see a use for? I also went outside and looked around but couldn't see anything else I needed to do. I could see some of the asteroids were blue but I couldn't move them? Any clues to what else I need to do?
