Colored Sprite Mod Android: Undertale

Good news: Since it’s just a sprite swap, the mod runs flawlessly even on older Android devices (Android 8.0+). No lag, no crashes. The touch controls remain clunky for Genocide Route bosses (looking at you, Sans), but the colors look stunning on an OLED screen.

What this mod does NOT do:

Yes, if: You’ve completed Undertale before and want a visual remix. The mod is safe (from reputable sources) and transforms the game into a pseudo-remaster.

No, if: This is your first playthrough. Play the original black-and-white sprites first. The mod is a dessert, not the main course.
