What if space were round?
Whatever leaves one side of the screen comes back from the other. Lines at the edge show where a moon will return, so you swipe up or down to meet it and catch it. Miss one and it turns hot: hot moons can't be caught, only dodged, and each one that hits you costs a life.

One codebase, two names
Weltraum first came out on 26 July 2018 as Kpy on the App Store. The whole codebase carried over into Weltraum, and version 1.6 is the biggest update since: a glowing new look, comet trails behind every moon, a guided tour with a globe that shows how round space works, and a result card after every round.
