`l` is the binary data for the levels, `m` is for the models. These are loaded in the map.js[1] and models.js[2]. JS13k, the contest this game was made for, has the 13kb size limit for a ZIP containing all necessary files. The build process[3] produces a q1k3.zip[4] that sits at 13309 bytes. Granted, the JS and assets without ZIP compression are a bit bigger, but when sent out over http with fast gzip compression there's still only around 15kb going through the wire.
