I like the mouse particles going to the middle.
power fluctuation every 5 levels is good.
The stars are easier to see, thank you.
If I click "Quit" the game still shuts down without a yes/no prompt. There is no warning.
After 20,000 clicks, everything else looks good. https://imgur.com/coCg7K3
Also, I hope you have the best of luck on your new game :)
