LD45 - Uh Oh Galaxy

A planet simulator with a side of chaos, made for Ludum Dare 45 Start from nothing.

Create and manipulate planets to cross items off your heavenly to do list, unlocking more and more powers as you go.

Note that not every item here is available from the get-go. Check the in-game tutorial for a more accurate listing.

Left click and hold to begin placing a planet. Drag the mouse to give the planet some velocity. When the outline reaches your desired height, release. Planets in proximity to other planets become hotter, with particles indicating their current state. Habitable planets lie in a certain temperature range. A planet not orbiting is a star, one orbiting a star is a planet, and one orbiting a planet is a moon.

Using the upper UI indicator changes the color of the created planets.  Gravity functions from larger planets to smaller planets only if they are different colors.

Using the lower UI indicator changes the type of planet added, once other types are unlocked. The black hole eats other planets but can be fully controlled by the mouse. The orbiting type of planet will 'lock' onto the nearest planet and choose a suitable velocity to orbit it. Gas planets cannot collide with other planets.

Use WASD to pan the camera. Use the scroll wheel to zoom the screen. Use Shift to slow down time. Use right click to drag an already placed planet.
