Does GOG refund games?

I'm curious to know, does GOG offer refunds for games that have been purchased through their platform? I understand that sometimes games may not meet the expectations of the buyer, or there may be technical issues that prevent the game from running smoothly. In such cases, is it possible to get a refund from GOG, and if so, what are the specific conditions and procedures that need to be followed in order to request a refund? I'm hoping to get a clear understanding of GOG's refund policy before making any purchases.
