Game Play: Move the mouse cursor (a crosshair) to aim your 'laser'. You must hit the
center void of the asteroid several times before it explodes (no need to click). You then
advance to the next level, where the asteroids move faster. The sole purpose
of this very simplistic 'game' is to clearly show you the effect of web browser (mouse) input
lag on HTML5 games.
The problem: The faster you move the cursor, the more that 'input lag' will affect your game play. Notice what happens with laser lines to the cursor location are turned on and compare the hardware cursor to the software cursor. Switch to a software cursor and notice the improvement.
The lesson learned: Play this game in web browser that has a TWO frame input lag (Chrome/Windows) and then play the game in web browser that has a ONE frame input lag (Safari/OSX), and you will notice that you play better (advance to higher levels) in a ONE frame delay web browser. Use the input lag detector at vsynctester.com to confirm the mouse input lag of your web browser.
