The page, which was taken down and now exists only in Google cache (keep clicking "cancel" to eventually see the content), implies that this new game has some new features. Achievements will be added, and the game will also include the ability to save games to the cloud - or is that Cloud? Finally, if you want to enjoy the game again without having to grind through it, it appears that this version of the game will even include a "character booster" that will allow you to edit your savegame to make grinding unnecessary.
Is this a real thing? We don't know yet, unfortunately. If it is, though, for the low price listed ($7.99 US!), I'd be up for owning a new version of this game.
