Is this a playable game, or some sort of game engine?

it's a rhythm game like stepmania (see funkin rewriten if needed as gameplay should be nearly the same) without too much of dependencies as I said it's compiled for native aarch64 linux and does not req extra steps aswell, only iirc libvlc, libvlccore and gamemode needs to be installed
