# picosky - common development tasks. Source lives in src/ (src/*.lua modules +
# src/cart.p8, which #includes them and holds the gfx/label/sfx/music data). The
# root picosky.p8 / picosky*.js are BUILD OUTPUT, generated by `make build`.
# `make` or `make help` lists targets. Override any variable on the command line,
# e.g. `make build PICO8=/usr/bin/pico8` or `make serve PORT=9000`.

# targets stay on the default (compressed-focused) minify - their limit is the
# compressed ROM size, not tokens.
