Lone Light (Prototype) is available at Gamejolt.com
In this game, you play as the source of light and you have to move toward the goal which is a white block to proceed to next level. As you are not visible in order to reach the goal you need to look at the size and direction of shadows that are created by obstacles and objects throughout the map. After some level as the game gets more difficult, the white blocks are also invisible and for finding the you have to look at the shadows of black objects. be aware to not hit the obstacles or the source of light would be destroyed also you cannot get outside of the range of the map. I hope you enjoy this game.
