It's #TreasureTuesday and today's pick is one of Programmer Michelle's favourite game series: Portal. Although both games were released over 10 years ago, they still hold an outstanding position in the field of puzzle and platform games. Their unique setting, the puzzle mechanics that were greatly expanded in the second game and, last but not least, one of the best antagonists, GLaDOS, made them iconic. Have you played it?
