#A Selene Backend with Canvas2D/JavaScript

#Installation

Import this backend with

moon add Milky2018/selene-canvas

Choose this implementation wherever the Milky2018/selene/backend is used. Add this in your moon.pkg.json:

{
  "overrides": [
    "Milky2018/selene-canvas"
  ]
}

#Instruction

Copy the provided index.html to the root path of your project.

Replace the source file path with your actual file path.

Build your project with

moon build --target js

Run the server with any Web Server such as

python3 -m http.server 8000

Finally, you can play your game by accessing localhost:8000 in your browser.
