Suggestions. Decrease the number of clicks slightly when using a mouse. The fingers hurt trying to go that fast. Alternatively, add spacebar support.

Absolutely unplayable on a phone. Bind to touchdown events on mobile. Click events have a 300ms delay. Make the game full screen for mobile.

Implementing Fastclick.js would make it work on the phone: https://github.com/ftlabs/fastclick

"FastClick is a simple, easy-to-use library for eliminating the 300ms delay between a physical tap and the firing of a click event on mobile browsers. The aim is to make your application feel less laggy and more responsive while avoiding any interference with your current logic."

It was really not fun for me until I realized that once the window has focus any key press gives a little boost. Its much more comfortable to stroke each key on the home row in rapid succession than to pound on one key :)
