Compulsion Games, the developer behind 2013’s puzzle platformer Contrast, has teased its next game.

At this point, we don’t know much about Compulsion Games’ new project other than that it won’t be a sequel to Contrast. “We haven’t ruled out doing one in the future, but after so long working on Contrast, we wanted to make something fresh,” the developer said in a post to its official site. “Something new and exciting. It involves masks, drugs and memory loss, but we swear it’s not a swinger’s party.”

In addition, Compulsion Games released the concept art images you can see here. It said that you should keep checking its website over the next month if you want to hear more about the game, or sign up for its newsletter.

Contrast was released on the PlayStation 4, Xbox One, PC, and last generation systems. The game blended 2D and 3D, using objects and their shadows to solve puzzles. GameSpot’s review gave Contrast a mediocre score of 5/10.
