In my opinion, this game would new more upgrades to make the game easier, like for example, a level 4 tube would be the mouth tube, except it could be recolored to show that It's better than recent upgrade ( It could also be another tube in her mouth, basically double tube). Another Suggestion would be a new upgrade called "More Juice" which multiplies the percentage of the juice after turning the lights green regardless of the size of the juice bar. To balance this, it would be the most expensive to upgrade and max out.
