Nice how when you finally lose, if you start a new game and just hit "reset" you get back all your previously earned upgrades even with zero points... the lagginess when you're trying to time your release sucks, and the scoring system is lame...
Locks up Chrome, freezes pretty bad in Firefox, and freezes for nice long pauses in menus in IE. And from what little I did get to play, it doesn't seem worth trying to diagnose...
autofire (in firefox, at least): hold A, click to another tab/window, then you can release A and go back and the bow will keep shooting until you tap A again. Can even go browse in other tabs while the game spams enemies into your line of arrows.
