Version 1.1 of NBody Gravitation has been released! This update contains a new episode with 20 more levels, bringing the total up into the triple digits.

Additions:

A new episode: The Target Mine! Back in the olden days, targets were all stationary and didn't react to gravity at all. Our new targetsteroids fix that, and we got 20 new levels out of this mechanic. I thought the same 60-second loop might get a bit old after 100 levels, so this update also contains new in-level music, set to play on episodes 2 and 5. It has a trombone.

Changes:

The title screen was changed to say "NBody Gravitation" instead of simply "NBody". Originally, the game's name was just "NBody", but this was changed in the last few days before version 1.0 released, after all the marketing materials were finished. I found out that an unrelated game called "n-body", with a hyphen, already exists on Steam, and I wanted to avoid confusion. Antimatter star balls now properly invert their colors instead of turning gray. The antimatter annihilation effect now has a purplish tint.

Click and drag to place asteroids, planets, and stars, then send them flying into the matching targets in a physics-based puzzle game where everything attracts everything. The levels start simple, but ramp up to include several moving parts and tricky solutions. You'll need to plan your placements carefully in order to win!

Featuring:

80 hand-crafted levels to master


An N-body gravity system where everything can move if something near it is heavy enough, or if something crashes into it. These puzzles are firmly grounded in real orbital mechanics!
(Aside from the targets. They don't move.)

Unique types of matter for unique puzzles:

Antimatter: Crash a normal object into it to launch it away and shave off some mass. Or avoid doing that if you need to keep something onscreen.


Exotic matter: It has negative mass, which means it pushes things away instead of attracting them. It's still attracted to normal matter, though.
