I think a flipper always gives you the possibility to get the ball back up, if you react fast enough (unless it goes throguh the middle).
But thats boring to me. So mechanics that allow me to influence the ball while its up, like you did, are really interesting to me. But if I can influence the ball at all times, I should be able to do something fun with it. "High risk high reward" and "low risk low reward" elements should be in it. That probably means redesigning the flipper though. Maybe the current flipper has that, but I cant really see these. They should be visually distinguished from each other and show how they are low or high risk areas.
I think I spent to much time with your game, but I really enjoyed it. Its really fun to always have a random mechanic that you now have to play with. Would be nice if I have to make the best out of each mechanic. So maybe having 3 lives and each a different mechanic, and at the end you get the score, or the mechanic just switches after a specific timeframe.
Well done :) Cheers
