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.
