How to restore the purchase of an app on my iPod?

I had bought the full version of minecraft but it got deleted from my iPod so I wanted to redownload it but I don't want to have to buy it again. Any way I can restore the purchase so I won't have to rebuy it?

Open up the App Store > Updates > Purchased and find the game. If the game requires a purchase to unlock the full game then there should be a restore purchases button within the app.

Yes you can.
Go to the App store>Purchased>then search for it and download it.
