The company explains that levels in Nebula Retro can be adjusted to any difficulty: “Levels are fully editable: as soon as you complete a level, you can edit it! You can add your own levels too without limit, making Nebula Retro almost infinitely expandable.”
The game displays a simple interface with a retro theme of 1980 and it has a sophisticated physics engine for a smooth animation and pixel-perfect touch controls. There are currently 26 built levels, however you can add as many more levels as you wish. Other available content: several ambient soundtracks, three graphic modes, anti-gravity, anti-rocket and hardware features (touch sensitive, realistic physics) to boost your experience.
