+# NuclearGravity
+## _The long-awaited sequel to NuclearPong (totally not)_
 
-Have you ever used gravity to escape to your base when your spaceship's fuel runs out? no? well you should
 
 
 
 
-In this new game you do exactly that. WASD controls camera, everything else is done via the mouse button.
+NuclearGravity is a game about... well, gravity!
+You have to strategically place planets in space in order for your ship to use their gravitational fields to get itself to its base.
+Some nice features include:
+
+- Realistic gravity
+- Practice to beat your score!
+- More coming...
+
+
+Installation is simple, just download the windows EXE release from the releases tab!
+If you're on linux, then clone the repo, and use debug.sh to launch the game. Linux binary coming soon!
+The prerequisites are **love** and **zip**
+If you're on arch, install the prerequisites with:
+``sudo pacman -S love zip
+``
 
 
-To launch the game, use debuggame.sh. Lua is required
