About

Substrate Entity

Features
Read full description

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.

A hundred thousand square meters of hedge. One night. One chest. Eternety Nightfall is a first-person gothic maze for iPhone and iPad. Rain on the stones, torchlight on the walls, heavy undead in the halls. The maze is 64ร—64 cells โ€” about 100,000 m2. Wall-following will not save you. Reach the courtyard, drop the sentinels that guard the chest, take the loot. Your clear time is your Game Center rank. PLAY โ€ข 64ร—64 rings and islands, one south gate, ~100,000 square meters โ€ข First-person pistol: fire, aim, reload, inspect โ€ข Weapon stickers: unlock marks and slap them on the pistol โ€ข Heavy zombies that go silent, then scream and charge โ€ข Courtyard sentinels lock the chest until they fall โ€ข HUD flasks, coins from the dead CONTROLS Move with the stick.
