"We approached Severin with the idea of an interactive riddle for our marketing campaign. Our prospects should try to answer challenging questions and open a safe. He came up with an appealing design that hit our taste with the first sketch. Then, within a concise time frame, he managed to provide a web-integrated solution that had a professional look but, at the same time, was incredibly fun to play. Severin's animated safe ultimately increased the conversation rate of our initiative."
