Emptonia

 Instructions
Emptonia is a 2D side-scroller puzzle game. Use WASD to navigate the levels. To swim, repeatedly tap W. The point of each level is to reach the exit point using features unlocked by touching colored orbs.

Each orb has a different special feature associated with it. Yellow allows the player to clear fog. Blue allows the player to fill spaces with water, letting the player move up or across large gaps. Red allows the player to break breakable walls. For red and blue orbs, the player must press ‘E’ to activate the ability (for instance, the player must press ‘E’ while touching the breakable wall for the wall to break).

The player can’t change from one primary color to another without changing back to white first. In order to do this, the player must touch a white orb.
