I see your points, but we made the planets have gravity to try and fit the theme, and when looking at games for the last game jam we noticed that they mostly have just one large level, and by the time we finished all the coding - it wasn't that new levels were hard to make - its that I wasn't fast enough at making new planet art. Also I don't know what the player is supposed to be either, to be honest, I didn't really know what I was doing :/
