• To help ourselves make levels, we built our own level editor using p5.js
• Made all of our sprites using Aseprite

Our level editor:

Dependencies

You'll need a nightly version of Nim because we need the -d:nimNoQuit from this pull request. To do so, install the latest nightly with:

Optionally, you can install binaryen to optimize further the binary size.
