GOG has made a change to its refund policy, simplifying the process and letting you get your money back even if you've played the game, as long as you request the refund within 30 days.

Previously, GOG's policy was a bit stricter than the likes of Steam's, as refunds were only guaranteed if the game hadn't been downloaded and played. Refunds could be appealed for other reasons, but not liking the game wasn't one of them. Now you don't have to worry about any of that.

If you've played the game, it's fine—you can still get a refund. It doesn't matter how long you've played for, either. Since most games can theoretically be completed in a month, the new policy seems pretty open to abuse, but GOG will be keeping an eye on refunds to make sure it's not being exploited.
