Drop a planet into empty space and watch gravity take hold of it. Pocket Galaxy is a 3D gravity sandbox where you place planets, stars and moons and then watch them orbit under real, physics-based simulation. Arrange a solar system exactly how you like it, then take it apart: heat worlds until they glow, freeze them solid, hurl asteroids, fire solar rays and set off chain reactions. There are no levels and no timers. The sandbox is the whole game, and the only clock is the one gravity keeps. What you can do • Sculpt entire solar systems from a near-infinite variety of worlds • Tune each world's gravity, size and orbit, even flip gravity to repulsive • Reach for cosmic tools: asteroid storms, solar rays, ice rays and explosions • Unlock new world and star types as you experiment • Discover procedural worlds, gas giants and glowing stars • Track your creations, and how life develops, in the Planet Journal • Save, load and screenshot your universe to share Relaxing and powerful at once, Pocket Galaxy turns real orbital mechanics into a toy box. Build a calm, life-bearing system, or smash it to particles; there is no wrong way to play it. This is the full paid version. No ads, no in-app purchases, no interruptions. Pay once and own the whole universe.

About

WormholeTrain

Features
Read full description

This is a game of wormhole maintenance. The game is to go through the wormhole and destroy and remove the cracks and lasts that destabilize the wormhole. Cracks are dodecahedral crystallites and lasts are icosahedral crystallites, both of which are toxins that are generated each time a wormhole is used. Both crystals are red. The green octahedral crystalline body is a structure called a cornerstone, which functions to stabilize the wormhole. If it is destroyed, the wormhole will collapse. Navigation through the wormhole is normally automatic, but can be switched to manual steering with the flip of a switch. Manual steering is a very exciting way to steer a spacecraft along a wormhole course, but it requires a high degree of skill and proficiency. However, manual steering consumes less energy and scores more points for destroying unwanted objects. Manual steering is performed by drag operation.
