I heard the suggestions: Please let me refund some upgrades. Now you can! But only all or nothing: Refund all upgrades, or stick with them. But don't worry, you'll get all your coins back.
With this new feature, you can find the best upgrade setup to reach the top the fastest. And to help you figure it out, there's now a timer!
The timer will start once the level starts and count on until you reach height 1200. Once you reach the 1200 mark, your time will also be submitted to steam, so expect some more achievements based on the fastest times!
