You really managed to fit it all in there, huh? I'm impressed at the scale of this, and the puzzles were really good. Not super difficult, mind you, but really fun little challenges that left me feeling clever when I found the solution. Music was great, too. I think the only thing I would have liked to see was a more climactic ending - maybe having gravity suddenly restored? Something flashy! Still, this was a cool idea and it made me feel smarter than I deserve. Nice work!
