## What is Weltraum?

Weltraum — a minimalist space arcade about orbit, timing, and nerves of steel.

You pilot a tiny planet. Swipe to move. Launch moons into orbit and keep them spinning — the longer they circle, the more stars you collect. Asteroids cross the screen. One hit and the run is over.

SINGLE PLAYER
- A gentle hand-drawn tutorial walks you through the controls
- Chase your personal record across endless waves of asteroids
- Every swipe matters — no menus, no grinding, pure arcade

VS MODE
- Local Bluetooth multiplayer — challenge a friend sitting next to you
- Split-screen head-to-head — first planet to fall loses
- Your stars are on the line: lose and you hand them over

BUILT FOR ONE HAND
- Every input is a single swipe up, down, left or right
- Portrait orientation, no gestures to learn
- Play on the train, in bed, in the elevator

DESIGN
- Clean vector art against deep-space black
- System font with full support for every script
- Haptic feedback on every launch and collision
- No ads, no in-app purchases, no account to create

10 LANGUAGES
English, German, Spanish, French, Italian, Portuguese, Russian, Japanese, Korean and Traditional Chinese.

PRIVACY FIRST
Weltraum does not track you, does not show ads, and does not collect your data. Bluetooth is only used for local VS mode, and only while you are in the lobby.
