The First 15 Minutes of Element4l (Vita)

Copied from MobyGames:Element4l makes the player control a body and having to advance past environmental obstacles (pools of water, lava pits, hills, and the like) till the end of levels.The only possible actions are switching the state of the body from gas to solid (ice, or rock) or fire, each condition characterized by properties. Ice advances by slipping, fire vanishes once in contact with the terrain, air floats when over lava pools, rock can gain velocity if on-air and falling on the ground. Except when it is into ice, transformation from one state to another requires energy. Energy is limited, but time restores it.It can happen that the body reaches a point it won't be able to leave: at any time it is possible to restart from the lastly reached correctly playable point.The Race Mode (available as a free expansion since October 16, 2013) is about reaching the goal in the shortest time. It is playable on 16 additional tracks, and in stages that have been reached in the main mode. It supports Steam leaderboards, and ghosts (both from online players and the developer themselves).
