You can request a refund for purchases made on the vintagestory.at web shop for any reason. We offer refunds within 2 weeks of purchase or 10 hours of play time, which ever comes first. However, even if you fall outside those limits you can still request a refund and we'll take a look. In Principal, if you don't like our game, then we also don't want your money. You should receive a full refund within about a week after your refund request.
Please write us a support ticket if you got the game on our site and would like to issue a refund.
If you have purchased the game through the Humble Store, itch.io or the Humble Widget, you will have to look up and comply with their respective refund process. These are outside our area of influence.
