Treasure Treasure: Fortress Forage (2009)

Trixie and Troy need to combine their talents, think carefully and blow things up to find all the treasures hidden in an abandoned castle. This is a two player split-screen puzzle/platform game, with local co-op only. You can use two joypads if you have them, but snuggling together on one keyboard is just as fun. The castle is pretty maze-like so there’s plenty of exploration to be done too.
