About Killing Substance
You control a sentient, corrosive blob that moves through a house. Your goal is to eliminate every person inside. You navigate by moving your mouse, which directs the substance across floors and walls. The main interaction is clicking on characters to dissolve them; some might try to run or hide, requiring you to chase them into different rooms. The pacing is quick, and the game is unforgiving if you miss a target or take too long. It feels like a tense, methodical hunt from the perspective of something inhuman.
