Hi there! I made an asset pack recently, and I thought it might be particularly useful for this jam.

The natural backgrounds are generally vague in what specific plants and trees are present, so they could make a good backdrop for the native plants, animals, and insects you’ll be bringing into… whatever it is that you choose to make. :)
They’re all CC-0 .png files, so they can be spliced, adjusted, and changed however you need.
With love, Kit
