I understand your point about clicking on the actual balls. It may seem like a good idea initially, but it dramatically increases the difficulty. That was the first implementation of the game, but I immediately ditched it when I found out that it made things much harder. The game's physics also does not reflect real physics since real physics makes surviving even harder.
I, unfortunately, couldn't create some interface elements for the scoring system, but the Windows version has a command window that tracks the high score if you'd like to see how high you can go. I have seen a maximum score of 55 right now, and my personal best, unfortunately, is just 29...
Thank you for giving the game a go and leaving a comment about it, I appreciate it!
