WebVersion
If you want to play on the web and wanna know why it's taking long, it cuz ofur speed, if you have dial-up it takes like 40 minute. Once it's done loading and a note to save all people from waiting again 40 minute to finish loading. Just hibernate ur CPU or restarting it then hibernate it.
DO NOT SHUT IT DOWN COMPLETEY
