I like your ideas! Different animations would not have been too hard to do. Mark also thought floating was a glitch lol!
The turning gravity on and off is very close to the core mechanic of a game that I'm working on right now. (You can play a prototype if you want. (It's called "The Gravity Machine"))
Thank you again for helping me to be a better designer!
(PS: no stealing "The Gravity Machine" main mechanic lol (I don't think you will tho lol (Do I say lol too much? LOL!)))
