Motespire
Motespire is a portrait, touch-first living-pixel reaction combat Roguelike. Drag one complete Ember, Tide, Moss, or Volt ampoule into the reactor four times. Repeats are legal. Every injection advances the same visible matter through gravity, density, lateral flow, steam rise, heat diffusion, combustion, crystal growth, bloom, conductivity, and catalyst motion before the final batch is measured.
