Thanks. For 95% of development, it "ramped up" twice as fast, but it got be overwhelming. It wasn't until the very end of development that I scaled back the ramp-up. Actually, I ended up having to scale back a number of things in this - ramp-up speed, audio (including adding the mute button), the background animations. It was seriously overwhelming at one point. It's kind of surprising how many minor tweaks this project required.
It should save your highscore for you, hopefully. Thanks for the report.
