Complementary

Complementary is a minimalistic 2D platformer with a twist: Players need to switch between two worlds on the fly to complete levels in a mix between action and puzzle elements. The player character’s abilities differ between the two worlds, so mastering how to utilize them is the key to victory.

Playing with a gamepad is recommended. 
Otherwise WASD should be used for movement.
