To play the game just drag and drop this link to your bookmarks bar or right click and bookmark it and play on any page by just clicking on it.
I have tested this game on Firefox and Chrome.
Update: Now a user can optionally login to the game allowing him to have the following advantages.
Note: Pls note that the url has changed cause I shifted the game to OpenShift(Its an awesome platform :) ).So you will have to add the bookmarklet again.
You can read more about bookmarklets and how safe they are, here .
Pause/Resume : Space
Restart : r
Exit : Esc
