Thanks for playing, and congrats on getting all 6!
So the funny thing is I did a tech demo re-recreating a scene from Banjo-Kazooie a few days before the jam with vertex lighting that looked much closer to what you'd see in a Rare game. I attempted to do the same here but I realized too late into the jam that I had set the base light level too high (I had base lighting completely off in the tech demo) and the terrain vertex density too low vertex lighting to work properly even though vertex lighting is enabled. The gold material on the bells and keys is also using a 32x32 reflection map similar to what Mario 64 used but I didn't UV map their models and the default coordinates are causing the map to get too distorted to see the details.
