About the game
Eternitubes 3D asks nothing of you beyond watching — it's a hand-built screen companion that uses procedural generation to keep producing fresh arrangements of one-of-a-kind tube-like forms. Every composition you see is brand new, a shape combination that has never existed until that moment. It was developed and published by FlippByte in 2026.
