@frankforce.bsky.socialhere's a top down view of all 8 tracks in SP13KTRA 🌈
every track is built procedurally, the full 3D road with banked turns, hills and crossovers, and all the scenery. each one has its own theme, palette, and building shapes.
and the whole game fits in 13 kilobytes! #js13k
@hogia.bsky.social@frankforce.bsky.socialfull soundtrack for my 13k game SP13KTRA is up on soundcloud

the mp3 is about 400x bigger then the game itself! 🤔 #js13k

@frankforce.bsky.socialhere's the magic trick behind how I fit 8 music tracks in my #js13k game SP13KTRA. 🌈🚀
every song is defined by a single number. 😯
the random generator uses 26 dice rolls per track for its parameters. i used AI to make this music bench to find a good seed to fit each level.
