Liked the physics of the drive. Note, you can farm the balls into x2000+ and soon unlock the whole game, maybe give them a max multiplier or have them despawn or deflate otherwise they are a source of unlimited money.
Text is hard to read and menus are not perfectly clear. ALso, didn't understand if "packing" has a purpose or just for fun.
The lack of timers or health makes a very easy and very relaxing game. Only two buttons during game-play. Make menus way more simpler and I think you'd have a hit game for kids or for relaxing.
