The Reflection Beta Version is now available! It is not the complete game so expect some minor bugs but otherwise, the game is completely playable.
Here's the description of the game:
The Reflection is a game that offers a brand new view on space and matter. The game explores the connection to an alternate dimension called The Reflection that contains all the matter of the world inverted. The portal to this dimension is characterized by a plane of water. From the surface, there appears to be simply a reflection of light, but submerging into the water reveals that this world is completely tangible, mirroring the world perfectly. Even moving objects and enemies are reflected, allowing players to interact with these from another angle (literally).
Every aspect of the gameplay is carefully designed to utilize and expand the possibilities of The Reflection. Portals throughout the world enable the player to travel from the underside of a surface in The Reflection to its corresponding surface (facing up) in the world. Some enemies exist in The Reflection and appear upside down in the world. Underwater sections of moving platforms disappear completely when reflected. The player also has a grappling ability that allows them to reach portals on the ceiling, which will become the floor once the player teleports to the corresponding surface in the world.
