Damn, thanks for the detailed report!
Thanks for the game! It is very enjoyable - it is kind of soothing/hypnotic watching the balls bounce around. It would be great to have this as an Android app so I could play it at night on my way to bed. Layout-wise it's already all good in landscape.
You might have it save your progress so you can exit the app and come back. You might remove the hover popovers which don't play nicely with mobile (ideally change them to little info boxes you tap to bring up the popover - then tap the popover to close it).
If you were to put ads in that box where you presently link to YouTube that would be pretty acceptable for most mobile gamers I would imagine - then you've got an income stream to support further development.
It would be cool to see the game built out a bit with a prestige mechanic (that just puts a base multiplier on - 2 to the power of the times you've ascended), more ball tiers and maybe even some new mechanics (I imagine balls that repel others or have reversing gravity, balls you can click to make them explode, "enemies" that eat balls but if you tap them you get the balls back plus a multiplier, a research lab where you research new balls, etc.)
