GemCraft LabyrinthAuthor : Game in a Bottle - 8 677 plays
After many years of searching, the entrance to the labyrinth has finally been discovered! From afar, you can make out a twinkling light, which is a sign that the treasure is indeed there. But there are hordes of monsters guarding the entrance and it’s your task to eliminate them. As you might expect from a GemCraft game, the aim is to create and combine gems, and then place them on towers to push back the enemy.
