Note
Because Klang is a 2D game, some laptops will default to running it off of the integrated Intel GPU. If you plan on playing Klang on a laptop, we recommend that you run the game off of your dedicated gaming GPU. (NOTE: This may have to be done manually.) For an optimal gameplay experience, we recommend playing Klang on desktop computers with PC monitors.
