It's normal Geometry Wave Dash but with 2 players (:! Press 'W' or use the mouse to move the red player. Press the space / up arrow to move the green player. Yellow coins give a 30-point boost and red coins do the same but with a hundred. Different portals change the game in multiple ways!
Thank you @nzi900 for Geometry wave dash. And as always, thanks to the Remixers™ for helping.
