Not sure that you can still download it from history if the developer has pulled the app and it's no longer available.You can still download the app from your purchase history and run it on the device you purchased it. If you purchased this on an iPhone 3G, then you are fully entitled to use the app on that device.
How much did you paid for this? $1.99? Do you expect the developers to work on remastering this game for free after ten years?
