120+ FPS | Uncapped frame rate, gameplay is capped at ~60 FPS.[3] Manually cap the frame rate at 60 FPS if the game appears to stutter. It is possible that on certain devices the gameplay can run at more than 120 in Windowed Mode.[4] |

Widescreen resolution
- By default, game renders internally at 1280x720 and then upscales the content to match selected resolution. It's possible to raise the internal resolution to 1920x1080, however most 2D assets are done for 1280x720 and thus are upscaled regardless.
