About

Substrate Entity

One row every beat. It forks every beat. You are a charge running an etched plate. The trace splits under you, and some of the branches it offers are already finished. Nothing marks them. You read ahead, you pick a side, you keep moving. Press the left or the right of the glass. That is the whole game. SEVEN STRATA Each one runs faster and darker than the one above it. When the colour turns, the tempo turns with it. CHARGE Every row costs you. The bright pads pay it back and stack your multiplier. The branch that keeps you alive and the branch that keeps you fed are rarely the same branch. NO ADS No timers, no energy, no currency, no in-app purchases, no account. It runs entirely on your phone. Portrait, one thumb. Sound, haptics and motion each turn off. More from Dro1d Labs: Pixel Pigeon for the stubborn life of a city bird, and War Pigeon for tactical stealth after dark.
