Datum Games is an independent game studio based in South Korea. We build short, difficult, honest games — no ads, no tracking, no dark patterns.
Orbital arcade
Slingshot a craft between planets using nothing but gravity and the timing of a single tap. Release too early and you fall; too late and you fly past forever. Named after the Oberth effect — the real principle that a burn is most efficient at the lowest, fastest point of an orbit.
Dozens of hand-built levels across four worlds, each introducing a new way for orbital mechanics to work against you: unstable orbits, phase gates, repulsors, black holes.
Coming soon to Google PlayOur games collect as little as possible. Oberth has no accounts, no sign-in, no advertising and no third-party analytics. Your progress stays on your device unless you deliberately turn on the online leaderboard, and even then it is a display name you chose and a completion time — nothing that identifies you.
