I was thinking, maybe a power up that increases the duration of all of your pre-existing power ups by a certain duration? Maybe by a multiplicative amount, or a set +10 seconds to all. I believe that this upgrade is balanced, as it can be good in many scenarios, but also can be bad to pick up if you have upgrades that you do not want, I.E. increased gravity. Thanks for giving me this opportunity to promote concepts that I believe can make the game more unique, and even more enjoyable.
