Multiworlds

You made one mistake, of touching the untouchable A magical artifact that was buried deep in the depths.
The world tore into multiple worlds, in each timeline, running parallel, but with minor differences. Now strive to fix the world, merging them back into one.
Control the player in multiple worlds, all parallel. Collect pieces of the original world which are scattered around the parallel worlds, and help put back the original world.
Jump into different echos of each world to avoid obstacles blocking your path. Collect the world pieces to protect your original world.
Game Mechanics:
Use W/A/S/D to move the player left/right/up/down and Q/E to move the player to Light World Echo and Dark World Echo. You can interact with items like walls/spikes/collectibles of the same World Echo as a player. Use F to flip the the current Echo World that the player is in. If you're in the Dark World Echo, jump into the Light World Echo, If you're in the Light World Echo, jump into the Dark World Echo. Hit the world edge (wall), and the player stops walking.
You start a level by queuing up actions using the W/A/S/D/Q/E/F buttons, and then hit the Simulate button to simulate the sequence. If you have collected all the World Pieces in the level, you will have stitched the fragment in the timeline, and you move on to the next level. Else? Level Reset. So strategize well, before you start the simulation. You can stop the simulation manually as well, but you still lose the points ;)
Look out for portals, you can use them strategically to jump through, and your walk continues. You can only use portals that are in the same Echo World as the player.
Use switches in the same Echo World to unlock/toggle the locks for certain World Pieces, or Obstacles.
