play "motherload"
Though I am not usually so cruel, I must say that simply duplicating X-Gen's Motherload and not giving credit is unacceptable, and it reflects poorly upon you as flash a developer.
In regards to playing experience, I still believe Motherload is preferable. If some significant new features were added then this would be a fantastic game. As of now though, Mega Miner's animation is choppier then Motherload's, and in such a close race, that makes Motherload a superior game.
