Square Enix has issued a second patch for Chrono Trigger on Steam, aimed at addressing some of the feedback it received from fans upon first release. This latest update grants more tailored control options and continues to give a visual makeover to the sprites and animated cutscenes.

According to the announcement, the big change comes to the battle UI. Now players will be able to choose between one optimized for gamepad and keyboard, or touch displays and maps. The other two major changes are cosmetic: first to "improve the look of the classic pixel art" of the character sprites, and second to increase both the resolution and display size of the animated cutscenes.
