Where the roots run deep, only descent remains. RADIX is a hyper-minimal one-tap descent game. Tap, hold, and guide a single root through procedurally generated earth. Chain depth combos. Reach the bedrock — then go deeper into the void. EVERY RUN IS DIFFERENT A world generator carves new caves, stones, and essence drops every time you play. No two descents share the same shape. THREE BIOMES, ONE BREATH TOPSOIL gives way to clay. Clay yields to BEDROCK. Bedrock cracks into the void where light no longer reaches and your roots are all that remain. A procedural ambient soundtrack shifts with the geology — drone tones for topsoil, deeper resonance for bedrock. DAILY CHALLENGE A new target depth every UTC midnight, the same for every player worldwide. Beat it and grow your streak. Streak bonuses scale up to +75 Essence per day. ROOT TREE Every drop you collect becomes Essence. Spend it to grow your Root Tree — faster descent, wider magnet range, deeper void resistance. BUILT FOR EVERYONE • 4+ rated. No violence. No microtransactions, ever. • Reduced motion mode for vestibular sensitivity. • Optional haptics, optional sound. Settings persist across runs. • Works one-handed, portrait-locked. NO ADS. NO ACCOUNTS. NO INTERRUPTIONS. Pure offline play. No advertisements. No in-app purchases. No login. Just you and the depths. A meditation on going down. Tap to begin.
