Ah, thank you!
It was my first time actually making anything with unity so I definitely made heavy use of the freely available assets in the asset store and various online tutorials, lots of figuring things out. Managed to throw together the background music in about 3 minutes as well, hahah - if only I'd heard of the jam more than a few hours before the deadline! Maybe I could have figured out how to sort the dodgy raycasting, dodgy health, dodgy audio, and added some menus. Ah well~
