The Legend of Crystal Valley is a Point n' Click Adventure game that brings the best qualities of the genre. It provides many hours of gameplay dozens of various locations (including many hidden locations), characters and puzzles. With beautiful 2D backgrounds and 3D characters and interactive objects, The Legend of Crystal Valley is an adventure game that will stick you into your chair until its last scene!

LOCV is using the latest 3D effects and features of your video card such as shader model 2.0 and 3.0, per-pixel lighting with many light sources, normal and parallax mapping and a whole lot of particle effects. These effects have been carefully optimized so users with slower PC-s can enjoy the game to the fullest. And if you have an even slower PC, you can always scale down these effects.
We've chosen to use 2D pre-rendered backgrounds over a full 3D environment to allow high quality images and remain true to the good old adventure game role models.
