Working with physics is a lot of practice... it's useful to know all the technical details, but once you press "play" you're always going to be surprised.

But you've got to start with technical details! Here are some useful resources for that purpose. These links are all Unity-based, as that's the engine we use (at Free Lives) and it's the engine we understand.

- If someone is interested in making a first person physics game, Dani (of Karlson fame) released some tutorials and source code: https://www.youtube.com/channel/UCn7E5qFz-BML6o7XnjtlytA This is a little bit advanced, and maybe isn't the most pure-physics direction to take this jam in... but if anyone wants to try a FPS game you shouldn't code this all yourself, rather start from what Dani provides here and then add your own elements.
