you're not satisfied one of our games, just let us know why and you'll receive a refund.
Note: a $3 (or €3) processing fee will be deducted to achieve the refund.
However, you can ask for a refund only one time. Once you received a refund for a game, you can't ask a refund again for the same game or for any other Mana Games' game.
If you already have asked for a free Steam Key, you can't ask for a refund anymore.
Thanks for your understanding.
