I'm wondering did you use any game engine or you made your own one during the jam? An interesting game of running a cheese factory. Btw, I used the same songs for the Global Game Jam last year. It brings back my memories.
Well I use LibGDX, which isn't really a game engine, but more just an engine to draw images on screen. I coded movement and everything myself.
And Kevin Macleod is amazing for game jams of course!
