Thought a bit about it, read a bit about it. More comments are welcomed but in the meantime here's what I suggest: - The left series of light would be used for an end game bonus. - Current game multipliers would keep multiplying the base score during game and be diminished when the ball drains. - After game, all multipliers obtained during the game would be 'restored' and the final end game bonus would be multiplied by that total. So you'd have a sense of what will be the end game bonus but there would still be a bit of mystery around it. - The end game bonus would be balanced such as it'd be hard to have it exceed the base score and even harder for it to massively exceed the base score. - Score, bonuses and multipliers events would be re-shuffled in the game.
