 A [gleam](https://gleam.run/) [rewrite](https://github.com/Acepie/GameAIBulletHell) of a bullet hell style game my friend and I made in college. The goal is mainly for myself to use gleam on a larger/more creative project. Uses [p5js bindings](https://github.com/Acepie/p5js_gleam) for running the project as a web game.
 
+## How To Play
+
+### Controls
+
+- Use the arrow keys or WASD to move
+- Press "space" to jump
+- Press "shift" or hold down the mouse button to fire bullets
+- Press "R" to restart
+
+## Features
+
+- Levels are procedurally generated
+- Enemies use A\* to find their way toward the player
+- Enemies avoid walls, pits, obstacles, and each other
+- Enemies jump over pits when convenient and possible based on current velocity
+- Enemy behaviors utilize behavior trees (patrolling until they spot the player, then chasing the player, and firing if within range)
+- The player can jump over pits and enemies, but not over obstacles
+- Pits instantly kill the player
+- After getting hit, the player and enemies are briefly invulnerable to avoid continuous damage
+- If the player kills all enemies in a room, they will be spawned in the next randomly-generated room
